      01 What is the Python programming language?

      The official definition that we’ll find on Python’s website reads:

      “Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.”

      But what does that mean? And what difference does that make to your business? Let’s analyze this statement one-by-one. 


      Compilation is the process of translating human-readable code into machine code and generating an executable file, which runs the operations defined by the programmers. 

      Interpreting involves an interpreter instead, i.e., a piece of software that executes a program line by line on the fly without producing a file to be run by the operating system. 

      Python technology is classified as an interpreted language, although there is some compilation involved in its execution. Instead of compiling into machine code, Python code is translated into a simple set of instructions called bytecode. These instructions are executed by a virtual machine and not a computer’s CPU. This has some advantages. 

      For example, interpreted languages tend to be more flexible, which enables easier updates and quicker releases. They are usually more compact than their compiled counterparts. The code is portable, which means you can reuse it in different platforms and deployment environments. Examples of interpreted languages include Ruby, Perl, and BASIC. 


      The most popular programming paradigm, the object-oriented approach, uses the concepts of classes and objects. They are used to structure the code into self-contained, reusable modules that can be easily stacked together. This modality enables code reuse, which speeds up development and usually facilitates troubleshooting and problem-solving. 

      Object-oriented programming (OOP) also leverages inheritance to avoid excessive re-work and speed up development. Java, C++, PHP, Ruby, and Swift are just a few examples of object-oriented languages. It is worth noting that while it’s object-oriented by design, Python can also support other programming paradigms.


      As a high-level language, Python has strong abstraction from machine language, being quite easy to understand – and use – by programmers. High-level languages are close to human language, which lowers the learning curve for users and facilitates coding. They are also machine-independent, portable, and easier to debug than low-level technologies. High-level languages in common use today include JavaScript, Java, Visual Basic, and C#.

      Dynamic semantics

      Python is also dynamically typed. Without going into technical details, this roughly means that it executes many operations (such as code extensions and updates) at runtime and doesn’t require as many data type declarations as statically typed languages. As a result, Python code is usually more succinct and tolerant to change. It can also be tested and debugged on the fly. Apart from Python, popular dynamic programming languages include R, PHP, JavaScript, Groovy, and Erlang.


      We should also add that Python is open source and can be freely distributed, also for commercial use. This helps reduce project costs through lower license fees, enhances compatibility with other standards and systems, and opens the door for custom code extensions that are sometimes impossible with a licensed technology.

      As a modular language, Python easily integrates with other languages and technologies, a worthy feature in complex projects that involve the development of hundreds of components. Code readability is another intrinsic characteristic of Python that’s highly advantageous from the project management perspective. 

      Python: basic concepts

      As a business-oriented professional, you don’t need to know how to code in Python (unless you want to, which we highly encourage you to do). However, some basic understanding of the language’s fundamental concepts will help you sail through project meetings attended by technical staff. 

      Python module vs. package

      You may have come across Python modules and packages; these two Python-related concepts are often confused. Let’s spell out the difference between them.

      Python module

      A module is simply a Python file containing statements and definitions (classes, functions, and variables). 

      Developers use modules to break the code into small and manageable chunks that make it easier to read and understand. A module’s definitions can be imported to other modules, eliminating the need to write the same code again. 

      An example of a Python module is, where acme is the module’s name, and .py signifies a Python extension.

      Python package

      A package is a hierarchical collection of modules. Think of it as a folder on your PC that groups related files. 

      Just like your folders, packages help maintain a readable, well-organized project structure. They serve as a directory that facilitates module tracking and management. Each package can be split into sub-packages, and modules can be imported across particular packages.

      There’s one important condition that every package must meet to be considered a package – it must hold a file The file can be empty, but without it, the code won’t initialize.

      Objects and classes in Python

      Another important distinction to be made in Python is that between objects and classes.

      As pointed out in the first section, many Python implementations subscribe to the object-oriented programming paradigm. In this approach, objects are a fundamental concept. 

      Each object is a unique collection of attributes and functions that act on these variables. These properties are defined in a class, which serves as a template for the object. The template is used to create specific object instances.

      Imagine a dog object. Class defines what attributes and functions an object needs to be classified as a dog. It will have a name, age, size, breed, color, etc. An object instance corresponds to an individual dog which has specific parameters of each of the attributes defined in the class.

      At this point, we will also need a construct that describes the dog’s behavior. If you want the dog to fetch a ball, what instructions do you need to provide? Let’s find out in the next section. 

      What are Python functions?

      Objects, classes, and instances deal with the attributes of an object. Functions and methods have to do with its behavior.

      A function is a block of code that a developer can run to carry out a specific task or return data as the result. In our case, the function fetch a ball would include instructions to be executed by your dog. 

      Each function may consist of parameters (variable names), and arguments (variable values) passed to the function when it’s called. Functions are reusable and can be called anywhere as they aren’t tied to particular objects or classes. 

      Methods also consist of a set of instructions to be executed in a given order. However, unlike functions, they cannot be called by their names. Each method is implicitly used for a specific object and class.

      Python’s popularity

      For the last few years, Python’s performance as one of the world’s leading programming technologies has been quite steady. Ebbs and flows happen, but the general upward trend dominates. Two main factors are critical here: Python’s high accessibility and versatility (to see how Python is used across industries, jump to What is Python used for?). 

      In RedMonk’s June 2020 Programming Language Rankings, Python takes the second position (no change compared to the previous ranking edition) as the most popular programming language. It is “the first non-Java or JavaScript language ever to place in the top two of these rankings by itself.”

      Although in Stack Overflow’s 2020 Developer Survey, TypeScript edged Python out by a narrow margin as the world’s second most loved programming language, Python has maintained its stronghold as the most sought-after technology – the fourth year in a row! Roughly one-third of the surveyed professionals would like to learn it. 

      According to the TIOBE index, Python occupies the third position as a top programming language, moving up by two positions in the last five years, and making a massive leap over the previous two decades, from 24th place in 2001. 

      Finally, a quick look into global Google Trends in the past five years validates the strong interest in the Python language across the world.

      Who created Python?

      Python was conceived in the 1980s and was first released on February 20, 1991, by Guido van Rossum. At that time, Van Rossum was a programmer at Centrum Wiskunde & Informatica (CWI) in the Netherlands, a government-funded research lab. His team was working on the ABC programming language that focused on user-friendliness and programmer efficiency. 

      The project turned out unsuccessful, but even as Van Rossum moved to other ventures, he hadn’t abandoned it altogether. He and his colleagues needed an easy-to-use scripting language for Amoeba, an operating system they were developing. That’s when the idea of Python hatched. The successor to ABC took after many of its core concepts and features, including:

      • high-level data structures
      • dynamic typing capabilities
      • focus on programming efficiency

      Want to learn more about Python backstory? Hear it from Guido van Rossum himself:

      Python Pillar - Guido van Rossum yt

      Later on, Van Rossum developed some of these characteristics into a set of principles underlying Python’s design philosophy. According to them, Python has to be:

      • “an easy and intuitive language just as powerful as those of the major competitors
      • open-source, so that anyone can contribute to its development
      • as understandable as plain English
      • suitable for everyday tasks, allowing for short development times.”

      Despite numerous updates and releases (the most recent major release of Python is version 3.9.2, with Python 4.0 expected to launch in the next few years), these goals still hold.

      Why is Python called Python?

      Time for some trivia. Contrary to popular belief, the programming language's name has little to do with the non-venomous constrictor. 

      As the story goes, Guido van Rossum named Python after the landmark BBC Comedy TV series Monty Python’s Flying Circus

      Whether Van Rossum was somehow inspired by his favorite show or just wanted to pay tribute to it, that we don’t know. But actually, there is some common ground between the comedy series and his programming ‘child’:

      • Both are incredibly popular in their respective fields.
      • Python makes extensive references to objects and concepts that appear on the show. For example, it uses the .egg distribution format, Lumberjack library, or spam variables.
      • Python fans will tell you that coding with Python is fun, experimental, and versatile. So is Monty Python’s comedy series.


      • Python has been around since the late 1980s, yet it remains in the top tier of the most popular and used programming languages.
      • The language was conceived to be highly readable, and it emphasizes programming efficiency and speed. 
      • As a high-level language, Python resembles human language, which reduces the learning curve and facilitates development.
      • Versatile and flexible, Python can be used in various applications. The interpreter is supported by mainstream OSs. 
      • Python is open source, which enables greater innovation and reduces software development project costs.

      02 The pros and cons of Python

      Several advantages of Python for your business should already come into view in the first section. Let’s bring them together and use some more compelling reasons why you should consider Python in your next software project.

      Python advantages for business

      If we revert to the official programming language’s website, we’ll find out that:

      “Python is powerful... and fast; plays well with others; runs everywhere; is friendly & easy to learn; is open.”

      That almost sounds too good to be true; nevertheless, Python does stand out among other programming languages in many respects. How? We will analyze the core Python advantages in this section, considering how they translate into added value for your business.

      Affordability and cost savings

      Developed under an open-source license, Python costs your business nothing to use. Anyone can download its source code, update it, and distribute it without obtaining costly licenses. Furthermore, most tools and libraries necessary for Python development (see section  Python: technology environment) are also free. As you don't need to cover any license fee, the project's total cost greatly diminishes.  

      Fast and efficient development 

      Efficiency is intrinsic in Python. Simple syntax translates to fewer code lines, while a high-level approach, code readability, and uncluttered formatting make life easier for programmers. Additionally, Python has an extensive collection of libraries, which facilitate and speed up development. All in all, these Python features mean your team needs to write less code to achieve brilliant results faster. 

      Mild learning curve

      Because of its relative simplicity and developer focus, Python is considered a great language to kick off a programming career. Close to natural language, it is quite easy to pick up, understand, and code – at least up to a certain proficiency level. Along with that, resources for learning Python, including free courses and tutorials, are widely available. 

      The mild learning curve allows us, developers, to pick up the language faster. But the fact that Python is so approachable also allows project managers or product owners to make more informed business decisions as they gain a better understanding and visibility of the developed software. Non-programmers like data scientists, statisticians, or financial analysts, also benefit from getting familiar with Python, which underlies many applications they deal with on a daily basis.

      Extensive range of applications

      We’ve already mentioned it a few times, and we’ll say that again. Python’s key business advantage is probably its adaptability. As a general-purpose language, Python is extremely productive, and it covers a wide array of uses across industries. 

      Python is commonly used in data science, AI, and machine learning projects. It can serve as a scripting language for web applications or as a standard component of most Linux and macOS distributions. Academic employees use it for their research. Python has also become a crucial tool for scientific computing, IT security applications, and the gaming industry. Enterprise software naturally also makes heavy use of the language. 

      → → To learn more about Python’s diverse applications, jump to the section Which industries use Python?.

      Flexible integrations

      Another advantage of Python is that it easily extends to other languages, like C++, PHP, or Java. This comes in handy, especially in distributed projects that span multiple teams and technologies. Python’s flexibility makes it possible to stick large software components together without timely and costly code rewrites. Additionally, you can leverage the speed and efficiency of Python to build quick product prototypes. Once they’ve been tested and approved, you can easily translate them into another supported language (like Java or C++) to release a production-ready version.

      Code portability

      Python follows the cross-platform philosophy, which describes a program's capability to launch on various platforms with no code extensions or modifications. The fact that you can write the Python code once and run it (almost) anywhere saves a significant amount of time and provides you with out-of-the-box multi-platform support. 

      Vibrant developer ecosystem

      The 19th edition of SlashData’s State of the Developer Nation report, published in October 2020, estimates that there are ca. 9 million Python developers globally; this is more than Java users. The report also suggests that more than 2.2 million members have joined the Python community within a year, a telltale sign of the rapid growth of the language's ecosystem.  

      What does it mean to your business? First of all, easier access to expert Python developers. Secondly, a robust community keeps the language’s technology stack relevant and updated. This positively reflects on the quality, security, and stability of your Python-based software. 

      → → If you’re interested in finding out more about Python developers’ community, check out the section Python community – who, what, where, and how?.

      Strong enterprise backing

      Here’s one more benefit of Python that may influence your decision about giving it a try in your next software project. Namely, it is a fully-fledged enterprise programming language. 

      Jump to the section Python for enterprises if you want to know what exactly makes Python an ideal choice for building mission-critical business applications. Here, let us just casually drop a few names that make extensive use of Python: MIT, Google, Facebook, NASA, AstraZeneca, Amazon, Instagram, Revolut, PayPal, Goldman Sachs, Spotify, Netflix, Udemy, Uber… and the list goes on.

      Python disadvantages

      We hate to admit that, but everything has its pros and cons. Even Python. As much as we admire the language, there are certain limitations to it that we have to account for:

      Speed limitations

      Code speed is probably Python’s greatest vulnerability. As Python needs an interpreter to execute, it tends to be slower than Java or C++. However, while we’re at it, it’s essential to distinguish between the CPU performance, a technical parameter, and code delivery time, a key indicator for you as a business person. 

      When we look at hard data, yes, despite regular optimizations, Python can still not crunch numbers as fast as some of the best-performing programming languages. But this rarely affects what probably matters the most to you: time-to-market. 

      In terms of the capability of turning your software idea into reality, Python tends to be even twice as fast and productive as “faster” languages. Several factors account for that, including Python’s compact code size, the language’s accessibility, or the abundance of 3rd party libraries. 

      Want to know more about Python speed? Let’s talk!

      We aren’t going to spend more time on this issue here; if you would like to discuss it in more detail, drop us a line

      Alternatively, we advise you to check out an excellent post by Nick Humrich, who expounds on this topic further. But in essence, Python’s speed limitations rarely have a significant impact on project delivery time.

      Not native to mobile development

      Another aspect that often crops up in discussions over Python’s deficiencies is the lack of native mobile support. Indeed, Python is not officially supported by Android or iOS, and it doesn’t have inbuilt mobile development capabilities. 

      This doesn’t mean, however, that there aren’t quality mobile apps using Python. The Python community has bypassed these limitations by releasing several libraries and packages like Kivy, PyQt, and Toga, which enable creating mobile apps with Python. 

      As our CTO demonstrates in his post, Python mobile development is possible, and with outstanding results, provided the development team has the requisite tools and skills. 

      Versioning headache

      Did anyone say: “Programming pet peeves?” December 3rd, 2008 was a breakthrough moment in Python’s history – that’s when Python 3.0 came to life. It brought some monumental changes, rectifying major flaws in the previous releases and massively simplifying the syntax. There was one problem, though. Py3K, as it was dubbed, was not backward compatible with its forerunner. This triggered a deluge of problems in development. For example, even though some versions became obsolete and the official support ceased, key libraries were not updated to work with the new version. 

      Compatibility issues may often result in extra development effort and require increased coding awareness. As a result, Python developers need to be well-versed on the feature compatibility to understand which version of Python to use, and make an informed choice of libraries, managers, and other tools.   

      A tendency for run-time errors

      Coding with Python is fast and efficient. Regretfully, it also creates more opportunities for developers to overlook potentially critical errors. Without explicit data type declaration, Python tends to be more vulnerable to run-time errors exposed when a program is already running. 

      This propensity of Python sometimes requires more detailed or additional testing, which may lengthen the QA stage of the project. Again, a solution exists. Python comes with a range of tools and libraries to create automated tests, which help speed up debugging.


      • Python was designed to be easy, fast, user-friendly, and intuitive.
      • It is an open-source technology, which cuts down project costs.
      • It’s also extremely versatile, which means you can use it in a range of applications. 
      • A myriad of frameworks, libraries, and tools facilitate and speed up the development.
      • Python blends well with other programming languages, and its code is portable.
      • While it’s a start-ups' favorite, Python is also widely used by global enterprises.
      • Python tends to be slower than Java or C++, and it’s more vulnerable to run-time errors.
      • It isn’t a mobile technology by design. Even so, you can still use it to create mobile apps.
      • Python’s biggest downside is the lack of backward compatibility between major releases.

      03 Python applications. What is Python used for?

      One of the key reasons behind Python’s immense popularity, besides the ease-of-use and rich library support, is its cross-domain, cross-industry application. Python is a multi-purpose language; thanks to its inherent structure and open-source nature, it applies to many fields, which we’ll explore in this section.

      Python for web and Internet development

      As of January 2021, there were nearly 1.2 billion active websites around the world. Carrying out successful business activities in the 21st century without an online presence is virtually impossible. For some industries, like eCommerce, every minute of website downtime translates to thousands of dollars in lost revenues. Additionally, being down for more than 15 minutes already affects your website ranking. And reindexing a website to make up for the lost rank is always arduous and, at times – unfeasible. 

      An hour of website downtime could potentially cost Amazon over $13 million in lost revenue.

      This explains why modern companies invest in reliable, tried-and-tested technologies to build their websites and web applications. Many of them chose Python as the backend technology for its diverse support libraries, organized data structure, and fast development capabilities. Python technology also allows creating data-intensive, dynamic websites with custom animations and an elegant look and feel.

      JavaScript is typically executed on the client-side. On the other hand, Python is primarily used to build server-side web applications that handle URL routing, managing HTTP requests, database access, web security, and other critical tasks underlying website/web app processes. The abundance of development tools, libraries, and packages that come with the language encourages rapid development. 

      →→ Do you find the distinction between packages, frameworks, and libraries confusing? Jump to the section Python: technology environment, which explains these basic definitions and examines the most popular Python tools.

      Python for data science and machine learning

      When it comes to data science, ML, and AI, Python’s a top pick. The language has a leading role in implementing machine learning algorithms, predictive analytics solutions, and data engineering scenarios.

      One reason for that is the profusion of data-oriented tools and packages that Python extends practically for any scenario. Numpy, Matplotlib, Pandas – these are just a few foundational libraries that simplify and accelerate data processing projects. They are instrumental for performing advanced mathematical and statistical functions, manipulating and visualizing data, and working with voluminous data sets. These resources are also well-suited to numerical programming and statistics. 

      When tackling machine learning and AI tasks, developers and data scientists alike may leverage tools like scikit-learn, Theano, and TensorFlow. These and other Python ML libraries facilitate work with neural networks, enable natural language processing, and streamline common machine learning and data mining tasks.

      Another factor contributing to the wide application of Python in scientific computing and machine learning is the language’s high accessibility. With its clear syntax and readability and an extensive set of support libraries, Python lowers the entry bar for beginners and non-programmers. This makes it the most widely used programming language in data science.

      Python for AI, machine learning, and data science

      The following are some typical applications of Python in the data science and machine intelligence context:

      • Credit card fraud detection
      • Movie recommendation system
      • Speech emotion recognition
      • Gender and age detection
      • Chatbot creation
      • Driver drowsiness detection
      • Traffic signs detection
      • Handwriting detection
      • Fake news detection
      • Image caption generation
      • Breast cancer classification

      Python for audio/video applications

      If Python is a general-purpose language, why not use it for developing audio/video apps? Python offers a wide range of multimedia libraries, such as GStreamer, FUPlayer, and Boxtream, that allow developers to work with images and sound. They are used, in particular, to:

      • record, edit, mix, and export audio,
      • play audio and video files in different formats,
      • edit voice and video material, 
      • stream sound.

      Additionally, there are also several Python modules libraries for audio/video conversion. These include soundfile, wavio, and pydub.

      Python GUI development

      Python is commonly used for developing extensible and usable desktop user interfaces with a minimum amount of code. Game developers can choose from a variety of open-source GUI toolkits and libaries, including PyQt, PySide, Kivy, and Tkinter, among other tools. The choice depends on the project scope and requirements, app type, and individual developer’s preferences. 

      The available features and platform/device support vary across frameworks and libraries. For instance, the Qt framework and related packages are cross-platform, so they greatly reduce the time needed to roll out applications to particular operating systems. Other tools, like Tinker, support developers with customizable in-built widgets to streamline the app delivery and reduce code size. Certain extension modules allow Python developers to create native user interfaces well-suited for modern touch-based devices.

      Python for business applications 

      Business applications need to be scalable and extensible and ensure fast and secure access to sensitive corporate data. And despite a common misconception that dynamically typed languages cannot deliver on these features, Python is well-suited for developing enterprise-grade software. 

      • As a highly flexible language with a huge catalog of tools and libraries for any use case, Python can easily adapt to changing business requirements
      • Python is compatible with numerous platforms and blends well with other programming languages (including Java, C++, Rust, and Go), an invaluable asset from the perspective of a large organization that works with hundreds of legacy and modern applications that need to communicate seamlessly. 
      • Besides, Python’s vast and well-maintained open source ecosystem attests to the language’s reliability and stability, which are essential ingredients of any business application.

      Python for ERP platforms

      Several recognized ERP systems (like Tryton and Odoo) rely on Python in their backend, leveraging its capabilities for fast development and effective code reuse. There are many advantages of this approach.

      Let’s start with time and budget savings. Coding in Python takes less time than using Java, a traditional technology for ERP implementations. Secondly, Python has a neat, organized architecture, where each business function is implemented as a separate module. This enables the rapid development of additional features as a business need arises. The clean, highly readable Python code is also easier to debug and troubleshoot if issues occur. Finally – a major advantage over Java – Python is a fully-fledged language that can be used at all levels, from core functions to scripting. Such an approach helps reduce system complexity, making it more flexible and resilient.  

      Python real-life examples –  famous companies using Python

      We have already named some prominent commercial Python users, but let’s examine some of them in more detail. Take a minute to consider several real-life examples of notable companies using Python daily.


      Google makes extensive use of Python, one of the officially supported technologies of the Mountain View giant. Most of the core search algorithms use Python, and a majority of Google’s web applications, including Google Drive.

      Developers at Google also work with Python to build test deployment and automation scripts, implement data analytics, create and launch monitoring tasks, and quickly launch utilities. 

      “Python has been an important part of Google since the beginning and remains so as the system grows and evolves. Today dozens of Google engineers use Python, and we’re looking for more people with skills in this language.”

      Peter Norvig, Director of Research at Google



      Python sits behind Instagram’s mammoth collection of meticulously enhanced selfies and travel pics. The company’s drop-dead gorgeous smartphone app is almost entirely powered by Python.

      Instagram engineers praise the language's simplicity, allowing them to iterate rapidly and try out new, bold product ideas. However, they also point to certain performance challenges related to the massive scale that the Instagram app needs to handle.

      “We initially chose to use Python because of its reputation for simplicity and practicality, which aligns well with our philosophy of “do the simple thing first.” 

      A quote from an Instagram developer’s blog



      Python technology is gaining traction in the finTech and banking sectors, and an increasing number of institutions are equipping their non-tech personnel with Python programming skills. One such example is the top-tier Citigroup. It has added Python to the training curriculum for its bank analysts to gain a competitive advantage and drive better clients’ solutions. 

      Notably, Citi isn’t an odd one out. Other banking, accounting, and financial organizations, including JPMorgan and Goldman Sachs, follow Citi’s footsteps, retraining existing personnel in coding skills and hiring top Python talent.

      “We’re moving more quickly into this (Python) world. At least an understanding of coding seems to be valuable.”

      Python game development

      The Sims 4, Battlefield 2, World of Tanks, Civilization IV – all these record-breakers use Python to perform different tasks. Dozens of Python game development libraries like PyGame, Pycap, and Pyglet have made it possible, extending crucial resources for fast game prototyping, testing, and debugging, among other capabilities.  

      The vast arsenal of Python tools for game creation is also very useful for budding developers who are yet to build their first game. They can take advantage of countless GUI elements, widgets, themes, and controls to facilitate the development of visually rich games in Python.

      Python for blockchain

      Versatile, flexible, and modern, Python is also an excellent choice to implement blockchain. By employing standard and extension packages (like Flask), Python developers may create individual blocks, code them into an immutable chain, and test and expose the chain by means of a REST API. Python’s simple syntax and concise code eliminate complexities and ease linking the blocks together in a secure and firm manner. 

      Drilling down into a specific use of blockchain for cryptocurrencies, Python also supports developers with a range of dedicated libraries. One of them is CryptoCompare, a leading service for crypto news and market information and statistics. Cryptofeed is another useful library. It allows streaming market data from various exchanges directly into the user’s app. 

      Python for microservices

      Considered a disruptive technology barely a few years ago, microservices have entered the mainstream, and many companies are rewiring their platforms to this architectural pattern. To do that, or to build their microservices-based platforms from scratch, they may use Python. 

      Python comes with a wide range of open-source tools to facilitate microservices’ implementation, the top one being Nameko. This dedicated and extensible microservices framework makes it possible to create a service that can respond to RPC messages, listen to events, and dispatch events on certain triggers, among other functions. The tool takes care of all connections, transports, and concurrency, allowing developers to create the service using regular Python classes and methods.

      Python for mobile development – yes, no, maybe?

      Mobile development is one of our fields of specialization at Ideamotive. And as much as we love Python, we have to admit that it isn’t our language of choice in this context. Python doesn’t come with in-built mobile development capabilities, and a while ago, we wouldn’t have recommended it at all for creating a mobile app. 

      However, things have changed, and Python technology is becoming an increasingly popular choice for mobile app development. 

      Several robust packages exist that allow developers to build powerful mobile app front ends with Python. The ones that our Python experts use particularly often in their projects include the Kivy framework for cross-platform Python programming, and BeeWare, a write once, deploy everywhere tool that empowers the creation of Python-based native mobile apps. Additionally, tools like Python-for-Android and PyJNIus, among others, further supply mobile developers with the capabilities to build performant apps using Python.

      04 Which industries use Python?

      A jack of all trades and a master of many, Python doesn’t limit its usage to one specific area. Multi-purpose, highly accessible, and user-friendly, the language is applied across various industries. Considering its strong inclinations towards data science, ML, and AI technologies, it’s hardly surprising that it dominates verticals such as insurance, banking, healthcare, or digital marketing, all of which heavily rely on data. 

      The core strengths of Python make it also an in-demand language for other applications. Thus, before we dive deep into Python’s technicalities and examine particular tools and libraries for machine learning, data analytics or data visualization, let’s have a quick look at industries that use Python in their solutions.

      Python for finance and banking

      Python has made it big in fintech, becoming one of the industry’s most widespread technologies. It belongs to the core languages at several huge-scale financial institutions, including Bank of America, Citigroup, and JP Morgan, powering financial analytics and accounting systems, banking platforms, and digital wallets and payments. 

      The language offers an assortment of tools and libraries that come in handy when building financial applications. They are primarily used for data acquisition, manipulation, and visualization and provide insurance brokers, bankers, and financial advisors with deep data insights. 

      NumPy, for example, is a basic Python package for scientific computing often applied in systems that perform statistical computations and risk analyses. The Pandas library is a frequent choice for financial data visualization and blockchain implementations. Other Python tools often leveraged in finance projects include pyrisk (to evaluate financial risk and performance), scikit-learn (to apply machine learning to banking and financial software), and Zipline (a dedicated library for trading applications).

      Common uses: financial analysis, calculations, data manipulation, business insights, payments handling, blockchain-based solutions

      Companies that use Python: ING Bank, Bank of America, Citigroup, Revolut, PayPal

      Python for eCommerce

      eCommerce companies make extensive use of large data sets to streamline the buyer’s path to purchase and optimize inventory levels. Additionally, faced with an increased shopper demand for a personalized experience, they increasingly leverage AI and automation techniques to provide product recommendations, enable omnichannel experience, and deliver bespoke services. To achieve these goals, many of them turn to Python.

      Apart from the data science libraries like NumPy, Pandas, or SciPy, which help with data aggregation, cleansing, and manipulation, eCommerce platforms benefit from the deep learning and AI capabilities delivered by Python tools and packages (including PyTorch, Keras, or MXNet). They use them to build powerful recommendation systems, analyze buyer behavior, and implement chatbot support. Some companies also employ natural language processing capabilities to add multi-language support to their websites and apps or enable voice search for a more convenient end-user experience.

      Common uses: buyer data analytics, product recommendations, cross-selling and up-selling, image recognition, speech detection, chatbot service

      Companies that use Python: Amazon, Walmart, Shopify, American Eagle, Zalando, eBay

      Python for real estate

      Millions of listings, thousands of clients, extensive sales histories; the real estate industry produces copious amounts of data. Data that – if handled properly – can lead to more informed, relevant, and data-driven decisions. Python provides a vast collection of libraries like PyDoop, PySpark, or scikit-learn that support real estate agencies and realtors. For example, Python-based software helps scrape data from property listings, analyze it and shortlist the right properties (take a look at this neat example of a simple Python web scraping bot that helps automate real estate deal screening). 

      Developers enhance real estate platforms with Python AI and ML libraries to deliver predictive analytics capabilities that combine historical data, behavioral analysis, and real-time information. Altogether, they enable real estate stakeholders to assess market demand accurately, develop accurate price valuations, and predict customer behavior to tailor the offering accordingly. Python is also used in the real estate context to cater to less elaborate scenarios. For instance, Python-based APIs enable smooth communication and data exchange between websites, databases, mobile apps, and other platforms used by agents, landlords, tenants, and potential buyers. Python software can also be integrated with IoT sensors and devices to power home automation and improve property management.

      Python’s use by real estate organizations is long-standing, as shown in this video (which dates back to 2015). In the clip, Dr. Aleksandar Velkoski, Director of Data Science at the National Association of Realtors, demonstrates how Python and Elasticsearch can be combined to build a powerful real estate search platform. 

      Common uses: data scraping, property and buyer insights, risk evaluation and price forecasting, streamlined property management, IoT and smart home

      Companies that use Python: Zillow, Opendoor, Insurami, Remarkably 

      Python for healthcare and pharmaceutical

      Since Python is the programming language of choice in data science and research, its use naturally extends to medicine. Again, it's impossible to list all its healthcare applications due to the abundance of practical tools, libraries, and packages (like pyhealth, MedPy, PythonMed, or Seaborn). Thus, we’ll name only a few that come to the fore. 

      First of all, Python presents the healthcare industry with predictive capabilities. Using Python AI and ML libraries, scientists develop sophisticated analytical tools that can detect diseases based on early symptoms or even predict them before any symptoms develop, based on individual patient’s medical data and history. The same solutions are leveraged to come up with an efficient, personalized treatment plan. Python libraries are also frequently used in bed occupancy management platforms and solutions that help predict the length of stay.

      Computer-aided analysis of medical images is another popular area for Python programming. Programmers and data scientists use Python code to implement deep learning in image visualization systems. Machine learning models enhance image diagnostics' speed, accuracy, and output, accelerating case review and reducing diagnostic errors. 

      Python is also frequently used to build health management platforms, from appointment scheduling software to self-service patient health portals. When we look at pharmaceutical companies, they often use Python-based neural network models for drug discovery. To “invent” a drug, AI algorithms sift through potential drug compounds and validate them against a massive database of parameters. Many extraordinary drug discoveries were made by applying this method. One example is MIT’s antibiotic compound, which can kill antibiotic-resistant bacteria strains. AstraZeneca is another well-known enthusiast of Python. The pharmaceutical giant uses it in its smart software for collaborative drug discovery.

      Common uses: outcomes prediction, disease detection, triage automation, image-based diagnostics, patient management, healthcare apps, drug discovery

      Companies that use Python: AstraZeneca, UnitedHealth Group, Philips, Sema4, Novartis

      Python for digital marketing

      Digital marketing is a significant beneficiary of Python, which is natural, considering that data analytics lie at the core of any digital marketing strategy and activities. Depending on the scope of work, digital marketers might leverage Python-based apps and services for data mining and analytics, campaign planning and automation, report automation, customer insights, and many, many more tasks. 

      Python's data science capabilities are used across various digital marketing fields, from website traffic analysis, through SEO and SEM campaigns, down to personalized email campaigns. Python improves marketing automation with readily available libraries that help manage repetitive data management processes and in-built modules that handle complex data science, AI, and engineering formulas.

      If you look for specific use cases, here’s a handful. You can use Python code to program solutions that gather survey data, collect lead or subscriber information, or track competitor products, prices, and promotions. Python scripts are suitable for automating massive file operations or repetitive data formatting. They may also help analyze campaign efficiency on different media and make predictions on customer lifetime value, churn, conversion, and other key marketing metrics. 

      A rich collection of Python libraries, such as Pandas, Matplotlib, Advertools, and Selenium, are useful for SEO tasks. They streamline activities related to data extraction and analysis, web scraping, and data visualization.

      Common uses: campaign scheduling and automation, lead analytics, campaign insights, reporting, audience targeting, SEO

      Companies that use Python: Facebook, HubSpot, Zapier, SEMrush, Mailchimp 

      Python for startups and SMEs

      By design, Python is an excellent choice for startups, which often work under time pressure and with low budgets and need to iterate bold ideas fast. The language is an extremely popular technology behind many MVPs and PoC solutions that don’t necessarily need to be flawless or fully featured but must be working and usable products.

      Several characteristics of Python make it appropriate for dynamic, fast-paced businesses and projects. We will name them here, without expanding on these points as they have been covered in the section Python advantages (for business).

      • Low-cost: With Python’s open source license and a host of free tools and libraries comes cost-efficiency, a major benefit for young companies on a shoestring budget.
      • Accessible: As Python is relatively easy to learn, many tech entrepreneurs choose it to build and test their pilot products.
      • Innovative: Python’s applications are limitless, and many of them include cutting-edge tech like AI, ML, data analytics, or blockchain. Perfect for innovation-thirsty startups!
      • Universal: Versatility is a strong asset of Python, so whether a startup needs to build a web app or automate tedious work, it can achieve both with one language.
      • Easy to update: Python’s business logic based on modules enables fast updates and rapid code changes, which are very common in the dynamic startup environment.

      Python for enterprises

      Because of Python’s (relative) simplicity, some people question its applicability in enterprise software. Unjustly so.

      While Python doesn't support all use cases (as no programming language does), it has been used in various large-scale projects with much success. The list of corporate establishments applying the language in their projects is infinite and includes names like Google, Netflix, Deloitte, IBM, NASA, PayPal, Microsoft, and Spotify.

      Until quite recently, the resistance towards Python in the corporate environment was nearly palpable. Global organizations preferred more conservative technologies in their projects, like C# or Java. 

      However, Python’s footprint within corporations started growing rapidly as enterprises began embracing open, cloud-based, and community-driven platforms (see Microsoft, for example, and adopting disruptive technologies that asked for a new programming approach. As a result, Python is now catching up with other languages, becoming the language of choice for many enterprise projects. 

      What features of Python have swayed enterprises towards the enhanced use of the language? Here are some suggestions:

      • Speed: The need for rapid code development and focus on feedback is no longer intrinsic to startups. In the highly competitive enterprise setting, if you don’t innovate, you lose. Python provides top market players with the ability to ship new features fast and apply changes immediately.
      • Popularity: Because Python’s community is immense, it is much easier for enterprises to assemble an experienced dream team to take care of their software development projects. Moreover, with easy access to seasoned Python professionals, corporate companies can scale resources up and down easily, according to their current needs.
      • Flexibility: Like startups, enterprises readily benefit from Python's versatility. As the language serves multiple purposes, one team can reuse it repeatedly to achieve various automation and optimization goals. A considerable advantage, which helps improve business processes quickly. 


      • Python is extensively used in industries that rely on vast volumes of data.
      • The language is favored by non-programmer users due to its high readability.
      • Healthcare, pharmaceuticals, and finance and banking all benefit from Python.
      • A large number of eCommerce and digital marketing platforms are Python-based.
      • One of the greatest beneficiaries of Python technology is the real estate industry.
      • Python is popular among startups who take advantage of its speed and flexibility.
      • Its use for corporate, enterprise-grade applications is constantly increasing.

      05 Python: technology environment

      As of Q1 2021, The Python Package Index, the official repository for Python, lists nearly 300,000 Python projects, 2.5 million Python releases, and 4 million files. These numbers prove two main things. One, Python is ubiquitous. Two, it verges on the impossible to count the ever-growing number of its frameworks, libraries, and packages. 

      Therefore, we’ll not go there. Instead, we will briefly go over the most popular and extensively used Python frameworks, tools, and libraries. The ones used by huge organizations to enhance large-scale application delivery and by agile startups to roll out MVPs and bring amazing apps to market in no time. 

      Without further ado, here’s all you need to know about Python tech stack when you talk to product devs and system architects. Enjoy!

      Framework, library, toolkit – what’s the difference? 

      Python comes with boatloads of specialized tools that make development easier, faster, and more convenient for software teams. But before we go over them, let’s get the terminology right. Here’s a little reminder of the differences between a framework, library, and toolkit.


      As implied by the name, frameworks provide developers with a skeleton architecture to build their software. Like the house foundations, they come with some boilerplate code, basic program flow, and low-level components. Engineers use them to code more efficiently and faster. 

      Using frameworks, Python developers can focus solely on the application logic instead of programming routine processes that are the same across different projects. Frameworks also help ensure that the code is easily maintainable and reliable.

      → → For a list of most popular and broadly used Python web development frameworks, check the section Python web frameworks.


      A library is a collection of packages (useful modules and functions) that developers can call from their code to streamline work. For example, common Python libraries facilitate the development of programs and features related to data science and visualization, computations, image manipulation, machine learning, or natural language processing. 

      Like frameworks, Python libraries help developers avoid reinventing the wheel and writing the same pieces of code from scratch every time. By doing this, they also reduce the time required to code and minimize code size. However, frameworks are highly extensible and may consist of a selection of libraries. Libraries, on the other hand, are usually less complex, and they can be used selectively. 


      A toolkit is a more abstract term, which essentially refers to a set of tools for developers that make the coding process faster and more efficient. Toolkits may comprise packages and libraries, as well as general methods and functions. 

      Python IDE, SDK, and API

      Apart from the above three concepts, you’ll also come across IDE, SDK, and API terms while managing a Python project. 

      • IDE stands for an Integrated Development Environment, an application that optimizes the programming process with automation. While not mandatory for development, it greatly reduces coding time and effort for steps such as code refactoring or debugging.
      • SDK is short for Software Development Kit, a collection of software used for developing applications. It can comprise code samples, documentation, libraries, debuggers, and other tools useful to build and deliver code on a specific platform.
      • API refers to Application Programming Interface. It is a definition of a protocol that can be used to exchange data between two pieces of code. APIs define the allowed data formats, the type of requests both applications can make, and other conventions to ensure efficient and secure communication.

      Python web frameworks

      Before we look through particular frameworks, there’s one small distinction to be aware of at this point. Python frameworks may generally fall into two categories: micro-stack frameworks and full-stack frameworks

      • Micro-stack frameworks – also known as micro frameworks. They are compact, simple, easy to use, and best suited to quickly build small apps, MVPs, and programs that are a part of a larger project. A few examples of micro frameworks include Flask, CherryPy, or
      • Full-stack frameworks – these are far more powerful and complex by nature. They provide everything developers need to build fully-fledged applications from the bottom up. Apart from delivering an extensive set of libraries, they also comprise other services, such as templating engines and data management components. Popular full-stack Python frameworks include Django, Web2py, and TurboGears.

      Estimating the cost of Python projects

      Below, we have listed the key cost areas that you need to factor in when evaluating the budget for your next Python-based application. 

      Project type and scope

      The first thing to consider when evaluating any software development project is the scope of work. To come up with a high-level overview of the necessary investment, clearly flesh out the desired end-product, together with its core features. This will also prove instrumental in outlining the project timeline and duration, which directly impact the budget. 

      The type of application also determines the project cost. For example, banking or healthcare platforms will require additional features that ensure enhanced security and regulatory compliance. A powerful eCommerce platform needs AI integration for personalized recommendations and other customer-centric features. And so on.

      Features and complexity

      Once you get a ballpark estimate, you can drill down into particular features for an accurate cost breakdown. Put together a comprehensive list of end features. Their scope and complexity directly impact the time needed for delivery, the team size, and, consequently, the project cost. Standard functionalities involve less effort and investment than custom options. The more sophisticated and unique the features, the higher Python expertise they require to develop. The seniority of your development team will also impact the total cost. 

      Don’t forget about prioritization. It will make it easier to trim down the requirements if the total cost estimation exceeds your planned budget. Drawing up a detailed feature specification at the start will help you minimize sudden expenses as you proceed. 

      Tools and licenses

      Accurate estimation of a Python project (or any software project, for that matter) must factor in the cost of tools used for its delivery. Unlike some other programming technologies, Python is a free software license; generic classes cost nothing to customize, and a vast majority of Python tools and libraries are cost-free. Nevertheless, it’s useful to determine the required toolkit at the start, at least when it comes to developing core features.

      At this stage, you’ll also need to remember about external cost factors related to the development of any web- or mobile-based application. These include the domain name, a hosting server, and design templates (unless you wish to create a custom-built design from scratch, which will raise the cost even further). 

      Design, development, and QA

      This factor covers several crucial stages, from research, through architecture design and wireframing, up until the delivery of project mockups and the final project launch on the production environment. Depending on the established project size and scope, your Python team will include three to +12 people to handle these activities. 

      Why is three the minimum? Unless we’re talking about delivering one or two extra features or a small extension project, you’ll need a project manager, a developer, and a QA specialist to efficiently proceed with your work. 

      As your project gets bigger and more complex, it will require new roles to be fulfilled, including UI/UX designer, architect, business analyst, and more developers and testers. Obviously, the rates charged by each of these Python professionals bear upon the project cost. Considering that most of them won’t be involved full-time, outsourcing some of these roles is the preferred option for many companies.

      →→ To check the standard rates charged by Python specialists worldwide, jump to Python developers’ rates

      It’s also worth noting that the large selection of Python libraries, frameworks, and other built-in resources further reduces development complexity and drives down the final project costs. Thus, Python’s development speed makes it a perfect candidate for rolling out prototypes and MVPs fast and cost-effectively. However, this benefit becomes less prominent in huge, multi-team projects where other project factors increasingly come into play.

      Software development pricing model 

      If you decide to hire Python developers to bring your project to fruition, another cost factor to consider would be the contract type. Depending on your requirements and project scope, you may choose between three standard types of partner engagements or go for a hybrid variant:

      • Fixed-price. You set the total project price based on the defined and approved work scope and the agreed deadline. In this arrangement, you pay the hired team for the exact work you ordered, nothing less and nothing more. Fixed-price is generally good for small, short-term projects with clearly defined scope, well-developed requirements, and limited budget. However, it gives you little to no control over the process, in addition to being inflexible.  
      • Time and material (T&M). Here, you compensate the hired team for the number of hours spent on the project and any expenses incurred (such as licenses, third-party tools, travel costs, etc.). It’s a highly flexible model that makes an ideal match for Agile projects, granting you complete control on the project scope and alterations. This approach enables dynamic decision-making, but in return, it requires you to be much more involved. Due to its highly flexible nature, time and material are usually more demanding in the timeline and budget tracking.
      • Outsourcing (dedicated team). Finally, the third engagement model boils down to extending your team without hiring and HR hassle. As in T&M, the billing is also based on the contractors’ hourly rates, with the addition of the management fee. The hired team works under your direction, and it can be scaled up and down easily, depending on the current project needs. Although it typically requires the biggest budget, this contract type is an excellent choice for long-term projects with a broad scope. Instead of providing ad-hoc, random people to take charge of your development, it serves you with a handpicked, dedicated team of specialists who quickly become familiar with your company goals and expectations and constitute a reliable extension to your core employees.

      Scope of integrations

      Software integration is one of the most labor-intensive and high-cost phases in software development. This process alone may set you back from $10,000 upwards. Large-scale, enterprise integrations can amount to $50,000-$100,000! Apart from integrating with multiple external systems and platforms, robust Python apps need to provide a database component and ensure swift and secure authorization and authentication for access.

      Fortunately, Python’s ingenious design makes it extremely effective for integrating with other languages (such as Java, C++, Rust, and others). Usually, Python developers don’t need to rebuild their code to communicate with them. Instead, they can simply leverage the existing Python APIs and Foreign Language Interfaces. 

      The same goes for third-party apps and interfaces. Python supports a variety of web protocols, including JSON, HTML, and XML. If you need to plug your app into PayPal or Amazon, provide support for the invoicing system, or get access to Dropbox or OneDrive files, Python will use secure APIs for that. As far as database connections are concerned, the language integrates with them very efficiently through readily available libraries.


      Often overlooked, maintenance is among the key factors influencing the cost of any software project. Web and mobile applications need to be regularly updated for seamless user experience and tight security. This entails extra costs following the software launch. 

      At the minimum, you’ll need to account for regular application updates, fixing any issues that may arise in the updated versions, and design and usability enhancements essential to meet the changing user preferences and reflect evolving design trends. Additionally, remember that if yours is a scalable app, any future updates and extensions will need to be budgeted individually. 


      Last but not least, don’t forget to include an adequate budget reserve in your estimate. It should be sufficiently large to account for both, the “known unknowns” and the “unknown unknowns” that may arise throughout the project. Depending on your project's complexity and duration, the contingency on your software project can amount to 20%-50% of the total estimated budget.

      06 Python versus other programming languages

      Why does Python live on land? Because it’s above the C-level. 

      Behind every bad joke, there’s always some truth. As one of the top languages used worldwide, Python stands above many programming technologies in terms of ease of coding, library support, popularity, code size, and readability. 

      But while it excels in many areas, Python is not an answer to all project needs. The language gives way to its counterparts in some respects. Understanding the core differences between Python and other popular programming languages will make it easier for you to decide which of them meets your specific business requirements.

      Comparing Python to other languages

      We already know Python’s strengths and weaknesses. So let’s see how it stacks up against other technologies. To determine this, we’ve assessed factors like performance and stability, ease of use, coding speed, available talent pool, and a bunch of more in our comparison below.

      Python vs. Java 

      We start from the most common technology comparison, i.e., that of Python versus Java. Both languages have been around for decades, and they share many similarities (such as strong cross-platform support, vast communities, and rich libraries). So how to decide which of them better fits your project?

      Key features

      Python and Java are both primarily object-oriented languages. As a result, their code is reusable, efficient to build, and relatively easy to maintain. However, one major difference is that Python is an interpreted and dynamically typed language. As a result, it benefits from highly readable and compact code, which boosts programmers' productivity. On the minus side, this feature of Python makes it slower than compiled languages, like Java. 

      Java’s performance depends on various factors, including version, hardware architecture, vendor, and OS. Overall, the language tends to demonstrate slightly better performance than Python. However, it still lags behind natively-compiled technologies like C or C++. Additionally, Java development requires significantly more code than Python, resulting in more time needed to review and maintain the code.

      Performance and speed of coding

      The requirement to use an interpreter instead of a compiler adds overhead to Python’s processing rate. Additionally, Python 2 is incompatible with Python 3, affecting coding speed, particularly for junior developers. Still, in many projects, the performance delay is insignificant, especially if we factor in other Python advantages, such as the low entry point and cost-efficiency.

      As a compiled language, Java launches slower but runs faster than Python. Since its code is checked before running, fewer errors usually occur at runtime. On the flip side, Java usually requires more work and code than Python to get things working. Its code is rather verbose and hard to read, which affects all stages of project development, from programming down to testing and updates. This also means that in many cases, when an issue emerges, Java developers will program things from scratch rather than trying to debug code. 

      Learning curve

      Clean code, simple syntax, robust community, and extensive library support add to Python's mild learning curve. The language has been designed for quick and easy learning, making it a suitable choice for beginners. Additionally, Python is a technology that business professionals such as data analysts or project managers can easily understand and analyze, which can considerably streamline project delivery.

      With a complex and broad-ranging programming environment, Java sits on the other end of the learning curve. As a result, it presents many challenges for junior developers. Learning it involves gaining a deepened understanding of APIs and design patterns, which takes time. 

      Fortunately, aspiring Java experts can rely on numerous free courses, tutorials, and interactive resources for learning. Additionally, even though the entry point for Java is pretty high, once the initial concepts have been grasped, the learning curve becomes milder.


      Large developer teams working on enterprise-grade software frequently turn to Java due to its stability and resilience. The language can also support AI and machine learning projects, but Python is much more common - and advantageous - in these applications. 

      While Java often powers web development and desktop GUI applications, Python makes the top choice in data science projects. It is also widespread in rapid prototype creation, MVPs, and quick ideation projects.


      The gigantic community of 12.5 million developers makes Java the most popular programming language in the world. Nearly 68% of software professionals surveyed by Stack Overflow know it. Consequently, the language has an enormous ecosystem of well-tested frameworks and libraries that cater to thousands of implementation use cases.

      However, Python treads on Java’s heels. With 9 million users worldwide, it is one of the most popular, loved, and used technologies. In addition, the current count for projects developed in Python is ca. 300,000, which further attests to the language's extensive use. 

      The verdict

      Python and Java are both influential languages, which provide superior results in their chosen fields of use. Overall, Java offers greater stability and is better suited to handle large, enterprise-grade projects spanning multiple development teams. On the other hand, Python is agile, dynamic, and intuitive - ticking all boxes to build prototypes fast and iterate quickly.

      If you follow agile practices or need to build software related to data science, AI, or ML, then go with Python. The same applies to small-scale apps with quick turnaround cycles. However, for most enterprise solutions and desktop GUIs, Java would be the standard choice.

      Python vs. Ruby/Ruby on Rails

      Next on our list is Python versus Ruby comparison. Ruby is a high-level, interpreted, general-purpose programming language developed in the mid-1990s by Yukihiro Matsumoto. In the words of its creators, Ruby “focuses on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.”

      Key features

      Ruby supports object-oriented programming, among other paradigms. Like Python, it is open source, so no license fee is required to use it. And similarly, it is a cross-platform and multi-purpose technology with a broad spectrum of applications, ranging from web development, data analysis, prototyping, and MVPs. Another common feature of the two languages is prioritizing programmer convenience and coding speed through easy-to-read syntax.

      Performance and speed of coding

      Python and Ruby are interpreted languages, which means they are inherently slower than compiled technologies like Java or C#. Nevertheless, they offer a range of optimizations (CPU enhancements, memory optimizations, garbage collector improvements) to make the code run orders of magnitude faster. And when it comes to development speed, that’s where both Python and Ruby get a head start.  

      Ruby is easy and fun to use (especially Ruby on Rails). The “convention over configuration” approach applies defaults in the code, accelerating development and reducing developers' efforts. Another Ruby-related concept is Rails "magic," a collection of abstract patterns that handle complex configurations such as setting up a server environment or wiring models and controllers. These patterns help reduce manual coding and make project development more efficient.

      Compared to Python, Ruby grants developers greater freedom. Nevertheless, while the fact that there are always several ways to achieve the same result often positively affects the developer’s experience, it may hinder efficiency. Too much autonomy can lead to unnecessary code complexity and project delays. Additionally, being one of the most permissive programming technologies means that Ruby can occasionally be unstable. 

      Learning curve

      Ruby's focus on simplicity and productivity streamlines the learning process and lowers entry barriers, especially for the Rails framework. In addition, the “convention over configuration” philosophy provides essential guidance for new developers and helps them build quality code from the start.

      However, because the language uses a unique approach to coding, understanding the principles of Ruby magic may initially take some time. The modest community size also means that budding Ruby developers may have it harder to start than Python novices. Hands down, Python is much easier to grasp for beginners.


      Ruby was built from the ground up to power front-end and back-end web applications. And it comes with a variety of frameworks that support this goal. The principal one is called Ruby on Rails, and it facilitates the development of database-backed web apps.

      Yet, as already mentioned, the language serves various purposes. Common examples include data analysis, prototyping, and proof of concepts. Sounds familiar? Yes, these are the chief areas of application for Python, too. 

      And when we think of companies taking advantage of Ruby and Ruby on Rails, their list has no end. From hospitality services (Couchsurfing, Airbnb), through fundraising and financial sites (Kickstarter, Indiegogo), to social media and streaming apps (Twitter, Hulu, Twitch) - hundreds of leading organizations build websites and web apps with Ruby.


      When we look at the community, though, Ruby doesn’t stand a chance with Python. Only about 7% of developers worldwide know Ruby. This number is insignificant when compared to more than 44% of professionals using Python. At the same time, although small, the Ruby community is well-knit and faithful to the technology. That’s because the language has been focused predominantly on web development and functional programming from the get-go. 

      Most Ruby experts work with the Ruby on Rails framework, but less popular tools like dry-rb, mRuby, or Hanami have been getting traction lately. All in all, it’s fair to say that while Python supporters are thick on the ground and diverse, Ruby followers seem to be more loyal and committed.

      The verdict

      In a nutshell, Python and Ruby are like a pair of siblings - they share some DNA but follow their own, separate paths in life. Ruby makes a great fit for web app development. Python, on the other hand, offers a much wider range of applications. 

      Thanks to fast performance, Ruby deals better with high-traffic sites and apps. On the other hand, Python stands out in applications that involve math and scientific operations conducted on massive data volumes. 

      Python vs. Julia

      Julia is a rising star in numerical analysis, data science, and machine learning programming. It was built from the ground up for high performance, offering blazing execution speed. What else makes it a worthy contestant to Python, and how to determine which language makes a better choice in your case? Let’s see.

      Key features

      Composable, dynamically typed, compiled before runs, and open source - this is Julia in essence. The language offers reproducible environments where you can repeat experiments without having to build code from scratch. Julia combines the benefits of dynamic typing and static typing; it is extremely interactive; and follows the same simple, easy-to-read syntax as Python. 

      Performance and speed of coding

      Designed to be ultra-fast, Julia beats unoptimized Python to the punch when it comes to the speed of execution in its target domains (i.e., data mining, machine learning, and scientific computing). In addition, code compilation allows Julia to solve many of the performance issues frequently encountered by Python. 

      The language has a full release cycle, including LTS (long-term support) releases, stable, and beta/nightly builds. So far, there have been no breakthrough releases that would cause any major disruptions to Julia’s stability. This may - though doesn't have to - change with version 2 in the future.

      Learning curve

      Top speed, robust performance, and ease of use make Julia the favorite language for 73% of data science developers. Nevertheless, the language has rudimentary documentation, which focuses strictly on data science and machine learning applications. As a result, applying it to other fields is incredibly ambitious.

      Besides, using Julia even for its dedicated uses requires much effort on the developers’ part. Unfortunately, the nano community also doesn't help aspiring Julia developers, as there aren't many colleagues to learn from if you’re a newbie. 


      One of Python’s core strengths is that it’s extremely versatile. It can support web development, automation, web scripting, and even enterprise app programming. 

      In theory, Julia is capable of the same. But while it’s true that Julia comes with a range of non-scientific packages, in practical terms, it is meant for use in scientific programming and not much beyond it. 


      Julia's supporters are steady, committed, but in short supply. Data scientists are the top users; hence, the language’s adoption in commercial sectors remains insignificant. And while two in three Julia users love it, their total count is drastically low. For now, a humble 0.9% of developers know Julia, making it the least popular programming language. It will take a long time before it turns into a computational science mainstay if this is ever going to happen.

      The verdict

      Created specifically for conducting scientific calculations and machine learning operations, Julia outshines Python in performance in these fields of application. That’s why many believe it might be ultimately replacing it in the long term. 

      Still, the technology is not recommended for projects outside of the data science and ML scope, as it requires explicit customizations and coding from scratch. On top of that, the meager community size and lacking documentation are the main obstacles to Julia’s widespread adoption. Also, Python is far more mature. It has been around for three decades now and is not likely to disappear any time soon. 

      Python vs. C#

      Python and C# are an entirely different kettle of fish. The former was created as open-source code from the onset, it powers agile, dynamic websites and web apps, and it’s a dynamically interpreted language built for developers’ convenience. The latter originated in the Microsoft solutions ecosystem and went open merely a few years ago. 

      C# was developed as a general-purpose programming language for the CLI, and it is statically compiled for maximum performance and stability. But, is it enough to beat Python’s merits?

      Key features

      C# is a well-established, powerful programming language that inherits from C & C++ while retaining simplicity. Developed by Microsoft, it shares many similarities with Java. 

      The language encompasses static typing, imperative, and functional programming disciplines. It can be compiled on different platforms and finds a broad application in mobile and desktop apps, websites, cloud-based services, enterprise software, and game development. Like Python, C# is object-oriented.

      Performance and speed of coding

      Microsoft-backed and mature (it was released over 20 years ago), C# is remarkably stable and consistent. The language imposes constraints on developers to create reliable and robust code. As a compiled language, it is also faster than its interpreted counterparts, including Python.

      That said, C#, like Java, achieves stability at the expense of code size and readability. Despite a highly organized structure, its syntax can be quite complex; for example, C# uses indentation, semi-colons, and curly brackets, and it is case-sensitive. These features generate hundreds of lines of extra code that take up valuable space - and require additional time to produce.

      Another factor affecting the implementation speed with C# is that the language is a stickler for rules. Miss a bracket or use the wrong variable type, and you're in for big trouble. As a result, developers need to validate each coded line. The added workload mounts the pressure to meet the deadline.

      Learning curve

      Although not as straightforward as Python, C# retains a relatively mild learning curve. The language offers lots of learning materials available for free, its community of developers is quite extensive, and many complex tasks are abstracted, so the aspiring programmers don't need to figure out how they work. 

      Still, C# has its unique challenges. For example, one needs a thorough understanding of certain principles and design patterns before starting to code. Besides, mastering C# goes beyond getting familiar with its syntax. To use the language, developers need to comprehend the entire Microsoft ecosystem, which may be overwhelming. Especially in the beginning.


      Based on its background, C# is the language of choice for developing Microsoft Windows apps. Large corporate teams especially favor it when building robust, extended business applications. But when we look at science computing, C# yields to Python and its enormous number of frameworks and libraries for data science, machine learning, AI, and computation. 


      Mature tooling, extensive library ecosystem, and active developers' community - C# has it all. About one-third of the world's developers use the language in their projects, which places it among the most popular programming languages (after Java and Python). 

      Additionally, C# developers can count on Microsoft support if they get stuck with programming or addressing code issues. That assistance may turn out priceless when project deadlines are nearing. Unfortunately, that’s something Python cannot provide.

      The verdict

      C# performs best in complex, enterprise-grade corporate software. The language is extremely powerful, allowing developers to build sophisticated, high-performing programs and web apps. Of course, for projects involving Microsoft integration or reliance on enterprise standard syntax and libraries, C# is the way to go.

      Theoretically, C# can most likely do whatever Python can do, and with better performance. However, its barrier to entry is significantly higher than that of Python. Many developers also find Python easier and faster to code. Therefore, for fast-paced, experimental, or showcase projects, we suggest going with Python. Also, when it comes to machine learning and data science, Python would be the winner.

      Python vs. C#

      Python and C# are an entirely different kettle of fish. The former was created as open-source code from the onset, it powers agile, dynamic websites and web apps, and it’s a dynamically interpreted language built for developers’ convenience. The latter originated in the Microsoft solutions ecosystem and went open merely a few years ago. 

      C# was developed as a general-purpose programming language for the CLI, and it is statically compiled for maximum performance and stability. But, is it enough to beat Python’s merits?

      Key features

      C# is a well-established, powerful programming language that inherits from C & C++ while retaining simplicity. Developed by Microsoft, it shares many similarities with Java. 

      The language encompasses static typing, imperative, and functional programming disciplines. It can be compiled on different platforms and finds a broad application in mobile and desktop apps, websites, cloud-based services, enterprise software, and game development. Like Python, C# is object-oriented.

      Performance and speed of coding

      Microsoft-backed and mature (it was released over 20 years ago), C# is remarkably stable and consistent. The language imposes constraints on developers to create reliable and robust code. As a compiled language, it is also faster than its interpreted counterparts, including Python.

      That said, C#, like Java, achieves stability at the expense of code size and readability. Despite a highly organized structure, its syntax can be quite complex; for example, C# uses indentation, semi-colons, and curly brackets, and it is case-sensitive. These features generate hundreds of lines of extra code that take up valuable space - and require additional time to produce.

      Another factor affecting the implementation speed with C# is that the language is a stickler for rules. Miss a bracket or use the wrong variable type, and you're in for big trouble. As a result, developers need to validate each coded line. The added workload mounts the pressure to meet the deadline.

      Learning curve

      Although not as straightforward as Python, C# retains a relatively mild learning curve. The language offers lots of learning materials available for free, its community of developers is quite extensive, and many complex tasks are abstracted, so the aspiring programmers don't need to figure out how they work. 

      Still, C# has its unique challenges. For example, one needs a thorough understanding of certain principles and design patterns before starting to code. Besides, mastering C# goes beyond getting familiar with its syntax. To use the language, developers need to comprehend the entire Microsoft ecosystem, which may be overwhelming. Especially in the beginning.


      Based on its background, C# is the language of choice for developing Microsoft Windows apps. Large corporate teams especially favor it when building robust, extended business applications. But when we look at science computing, C# yields to Python and its enormous number of frameworks and libraries for data science, machine learning, AI, and computation. 


      Mature tooling, extensive library ecosystem, and active developers' community - C# has it all. About one-third of the world's developers use the language in their projects, which places it among the most popular programming languages (after Java and Python). 

      Additionally, C# developers can count on Microsoft support if they get stuck with programming or addressing code issues. That assistance may turn out priceless when project deadlines are nearing. Unfortunately, that’s something Python cannot provide.

      The verdict

      C# performs best in complex, enterprise-grade corporate software. The language is extremely powerful, allowing developers to build sophisticated, high-performing programs and web apps. Of course, for projects involving Microsoft integration or reliance on enterprise standard syntax and libraries, C# is the way to go.

      Theoretically, C# can most likely do whatever Python can do, and with better performance. However, its barrier to entry is significantly higher than that of Python. Many developers also find Python easier and faster to code. Therefore, for fast-paced, experimental, or showcase projects, we suggest going with Python. Also, when it comes to machine learning and data science, Python would be the winner.

      Python vs. Golang

      Publicly released by Google in 2012, Go (Golang) emerged to rectify the defects of other widespread programming languages. It was supposed to retain C’s static typing and runtime efficiency, match Python’s readability and usability, and add a dash of high-performance networking and multiprocessing. Was this attempt successful?

      Key features

      Go is a statically typed, compiled programming language created and maintained by Google.  It takes after the C-family programming languages, adding a garbage collector on top to handle memory leaks. One of the principal assumptions behind Go’s creation was to ensure superior readability and simplify code development. The goal was to get a performance and speed boost and make programming easier. 

      Performance and speed of coding

      Go is quite a new technology. As such, it includes plenty of modern features to improve stability, such as garbage collector, memory safety, or structural type system. As a compiled language, Go is also extremely performant. Evidence shows that it can work up to four times faster than Python or Java. Small syntax and support for concurrency additionally further boost its execution speed. 

      But when we examine coding speed, things don’t look quite as rosy anymore. Compared to Python, Go’s code is much more verbose, requiring more development work. For example, a function that takes a few lines in Python eats up much more space when delivered in Go. For that reason, Go is not suitable for experimental development and quick project validation.

      Learning curve

      For developers who are familiar with C or Java, Go will be quite easy to master. However, complete beginners may initially struggle with understanding some of its concepts. Still, Go's syntax is compact and clean, and like Python, the language prioritizes code readability. This makes it learner-friendly and lowers the barrier to entry.


      Originally, Go was created for system programming, but the range of its applications has expanded since. The language provides great support for scalability, which makes it suitable for working with large data sets. It is also a popular choice for implementing microservices-based software architectures, cloud computing apps, and cluster computing software. Many high-performing e-commerce sites also make use of Golang.


      Barely a teenager, Go is still a relatively young language, so understandably, it cannot match Python in community size and access to resources. As a result, developers may occasionally find it hard to get the required tools.

      But Go's young age also speaks to its advantage. All the existing code and resources are relevant and up-to-date, and they are well-suited for modern project needs. And the language's community, though compact (only about 9% of developers worldwide use Go), is very active. When we consider documentation, Golang comes with a comprehensive programming ecosystem comprising editors, IDEs, and plugins that speed up and facilitate coding.

      The verdict

      On the surface, Go and Python are quite dissimilar. But, in reality, they share some fundamental approaches. Both languages serve the purpose of making programming as fast and efficient as it gets. They also focus on streamlining the developer’s experience and supporting emerging technologies.

      Go takes the win when we consider code execution performance and speed. By contrast, Python comes out ahead in community support and language versatility. In many cases, Go makes a valid alternative to using Python. The ultimate choice between the two depends on your project size, goal, and priorities.

      Python vs. SQL

      You may think that setting Python and SQL side by side is like comparing apples to oranges. That’s because Python brings associations with data science software, software prototypes, or full-scale web apps, whereas SQL is a query language. 

      But one of Python’s greatest merits is that it can be used for conducting relatively simple tasks, like retrieving and presenting data in various formats from a collection. And that’s precisely the perspective we will assume to make the Python versus SQL comparison.

      Key features

      SQL, or Structured Query Language, dates back to the 1970s (!). It was created to serve one main goal: to define queries that retrieve specific data from database tables. This standardized language is an essential tool for anyone working with relational databases, reporting, and dashboard analytics. SQL statements perform tasks such as data update and retrieval from common relational database management systems (including Oracle, Microsoft SQL, or Amazon RDS).

      Performance and speed of coding

      As a powerful query technology used to communicate with databases, SQL is highly performant by design. It allows retrieving huge volumes of data quickly and efficiently and conducting various data operations in no time. Moreover, the language can handle a large number of transactions simultaneously and allows to carry out complex database queries comprising multiple steps.

      At the same time, SQL’s predefined and inflexible data model requires introducing major adjustments on every data migration or data model change. The same applies to managing data conversions between SQL and other languages - it can get tough, so the process requires some expert skills.

      Learning curve

      SQL is a language that needs a whole different mindset than most 'typical' programming languages. It doesn't generate countless lines of code. Instead, it uses a handful of operators and basic syntactic rules. 

      While extensions of the main queries exist, to conduct most database operations, it’s enough to use a handful of operators, like “Select,” “Insert,” “Update,” “Delete,” etc. From this perspective, SQL is fairly straightforward, even for non-programmers. Additionally, as a standardized language, SQL offers robust support to all learners and users. 

      But while we may risk a statement that SQL is SIMPLER than Python (fewer concepts, smaller grammar, user-friendly syntax), it doesn’t mean it’s EASIER to learn. Surely, up to a certain level, the effort required to get familiar with a few SQL commands is much lower than getting into the nitty-gritty of Python. But getting proficient at SQL is certainly not a walk in the park.


      Examples of industries that rely on SQL include finance: banking apps, payment processors, reconciliation engines; social media: managing profile information, applying database updates (e.g., when a new photo is uploaded); media & entertainment: retrieving songs/books from the library, storing and updating user preferences, and many more.

      But even though SQL is one of the most widely-used languages in business, it rarely comes standalone in applications. Business intelligence tools, database queries, and back-end data science apps all build on SQL, but not as the sole technology.


      Well-known, popular, and established, SQL has a gigantic worldwide community. Nearly 57% of developers know it. The most popular SQL databases like MySQL, Oracle, PostgreSQL, or Microsoft SQL Server have millions of independent and corporate users. 

      The SQL ecosystem is used by over 60% of organizations globally. So despite recurring rumors about the technology's demise, it looks like SQL has retained business relevance, especially as it is increasingly applied in big data analytics and data science projects.

      The verdict

      As of today, SQL remains the go-to language for database queries. Using Python or another language just to mimic the SQL functions in most cases would be redundant. However, SQL is only capable of pulling data and combining it from multiple tables. Suppose you need to conduct more complex operations, like manipulating data or transforming it to other formats. In that case, the language won’t meet your needs, as it offers a limited set of commands. 

      That’s where Python steps in, with its ability to experiment with large pools of data. It offers many purpose-built frameworks and libraries for data analysis, manipulation, and visualization; they work particularly well with structured data sets. As a result, the sky's the limit when it comes to Python-based data management. Of course, provided that you have a team of expert Python developers on board.

      Python vs. Rust

      Compared to Python, Rust is a completely different beast, not only because it is a compiled language. Indeed, the principles underlying Rust are anything like Python paradigms. But despite core differences, some commonalities between the two programming languages do exist. What are they? Find out below.

      Key features

      According to its creators, “Rust is blazingly fast and memory-efficient.” Certainly, the language promises to solve pain points present in many other languages, such as performance lags and high memory consumption. At first glance, its syntax is very similar to that of C/C++  but with improved memory safety, easier concurrency, and pedantic compiler checks. 

      As a result, Rust enables writing stable and secure code very fast. Additionally, the language is memory-efficient. Also, by reducing the risk of obscure code, it encourages long-term maintainability. All of that positively impacts your project.

      Performance and speed of coding

      Rust takes pride in being a highly productive language. It offers diverse integrated tooling that speeds up code development with features like auto-completion and multi-editor support. 

      Like Go, Rust belongs to the younger generation of programming languages, and it applies similar methods to achieve top reliability and performance. These include the garbage collector, for more performant memory access, and compilation directly to machine code, for increased coding speed. Besides, Rust makes it possible to add performance optimizations. For that reason, it’s a perfect candidate for projects that prioritize speed and rely on CPU-intensive operations.  

      At the same time, Rust is still a low-level language. Consequently, it generates much more code than Python, which lengthens development time. Also, the need for external dependencies can be a potential issue for developers working with Rust. Finally, Rust’s framework and library documentation can be very confusing. 

      Learning curve

      Rust has its quirks, and some of its concepts like ownership and aliasing control are completely new to most developers, even those experienced in other technologies. These robust features require much more time to understand than Python basics. Even elementary things like splitting code into different files require getting familiar with long pages of Rust documentation. It can probably take weeks before a newbie feels comfortable using the language. 

      For that reason, Rust may be quite hard to pick up on the go. It is more suited for professional programmers with a solid grasp of other languages. That’s the exact opposite of Python, which doesn’t require any coding skills. 


      Rust code conforms to four main concepts in programming: procedural, parallel, functional, and OOP. Therefore, Rust is a universal language that can be applied in many areas. These include programming client applications and web servers, blockchain, building own operating systems, writing engines for browsers and games, and many others.


      Even though Rust remains a niche technology - known by only about 5% of developers worldwide - most of its users are die-hard fans. A staggering 86.1% of Rust users love it. This makes it the most loved programming language in the world, surpassing TypeScript and Python. 

      Furthermore, the language’s adoption rate is steadily growing. Considering the support Rust provides for cutting-edge implementations, we might see it permeating the mainstream shortly.

      The verdict

      Because they are quite different, we wouldn’t consider Python and Rust as competing technologies. Instead, both languages have their specific fields of application and unique strengths.

      For example, Python shines at scientific computing, which isn’t something that Rust is likely to be doing any time soon. Likewise, it doesn't make much sense to write shell scripts in Rust if you can implement them easily in Python. 

      Still, Rust is a very powerful language with a solid foundation, liberal license, supportive community, and a democratic approach to language development. Its future is bright, and if you are interested in developing your project in Rust, we are happy to help!

      Python vs. Bash

      Bash, available by default on Linux and Mac OS devices, is not really a programming language. Instead, it’s a user shell that interprets user commands and exposes an OS's services to a human user or another program. 

      But the reason we included it in this list is automation. Like Python, Bash can be used to automate the execution of tasks and reduce manual effort. So how does it look side by side Python in this context?

      Key features

      Bash typically runs in a window terminal to read and execute shell script commands. It can also be used as a CLI programming language to perform basic tasks. Bash provides a simple yet powerful way of interacting with the device to perform calculations, manipulate files, and launch programs from specific directories, among other tasks. The shell requires no third-party apps to be installed and does not deal with any frameworks. 

      Performance and speed of coding

      Bash launches quickly (faster than Python) but has poor execution time performance. However, it is sufficient for the uncomplicated types of operations that Bash traditionally performs. 

      The language was first released over three decades ago, and it is pretty stable, as updates occur rather infrequently. It comes preinstalled in most Unix systems and can be directly typed in the command line. 

      Bash lacks sophisticated functions, objects, and data structures, which facilitates coding. For the same reason, it’s impossible to accomplish many computations or data tasks using Bash. In any operations that involve managing files and streams of text, Bash is sometimes a quicker and more efficient alternative to Python and other languages. But its simplicity greatly limits its use in more difficult scenarios.

      Learning curve

      Very simple and practical, Bash is intuitive and easy to use. There are plenty of resources, articles, and tutorials available on the Internet to support learners. Usually, they are sufficient to gain a fundamental understanding of Bash within a few days.

      A person with no programming experience may initially struggle with understanding how scripts and commands work. Yet, Bash remains one of the easiest technologies to learn, especially for people with some prior knowledge of programming languages. However, knowing and using Bash are two different things. The syntax for more complex general-purpose programming tasks can be confusing and unintuitive, even for seasoned programmers.


      Bash scripts serve many purposes, like executing shell commands, automating simple tasks, or running multiple commands at once. In addition, they make an admin's life easier by streamlining some activities and dealing with large amounts of text and files. However, it's usually more beneficial to write scripts using a programming language like Python when things get more complex.

      Python can be used for writing shell scripts using projects like scriptine. There are several advantages of such an approach. First of all, replacing complex shell scripts with Python code often simplifies coding and makes it more efficient. Secondly, Python offers more granular controls over memory use in apps that go beyond shell programming. Finally, using Python means you can also deploy some of its data calculation or analytics features, which isn’t possible with pure scripting. 


      According to Stack Overflow's developers' survey, one in three developers knows Bash. Nevertheless, Bash knowledge is usually more of a side effect of managing servers and automating processes, so it's hard to speak of the Bash community as such. Normally, there's no need to look for dedicated Bash developers.

      The verdict

      With Bash and Python, it shouldn’t be either one or the other. Simple administration tasks (like creating a directory or deleting a file) can be handled easily by a Bash script. But when managing complex data structures or running sophisticated calculations quickly, you will be far better off with Python. Additionally, Bash lacks essential features and resources to support agile programming, so it won’t be a good choice if you’re following that approach.

      Python vs. R

      When it comes to data science programming, Python and R go neck and neck. They both are open source, modern, and loved by their communities. With so much common ground, what are the differentiators?  

      Key features

      R was developed nearly 30 years ago by academics and statisticians. As a result, it has a rich ecosystem of libraries and packages for deep analytics, statistical analysis, and data visualizations. The language relies heavily on statistical models, offers cross-platform support, and can perform complex operations on various data types, from vectors and arrays to matrices and images.

      As an interpreted language, R doesn’t need a compiler. Like Python, it offers full compatibility with many other programming languages. R also interacts smoothly with databases.

      Performance and speed of coding

      Even though R was created specifically for developing statistical software and carrying out data analytics tasks, its performance leaves a great deal to be desired. For example, packages are much slower than those of MATLAB or Python. Additionally, the language uses much more memory than other technologies, especially when working with large data sets.

      Still, thanks to various built-in functions, checking statistical hypotheses often takes only a few lines of code. Moreover, basic statistical methods are implemented as standard functions, which further accelerates development. Comfortable and clear language constructions are a definite advantage for non-professional programmers. Overall, when used in its target domain, R is a highly productive language for development.

      Learning curve

      Despite all its benefits, R often has a reputation of being difficult to learn. It certainly needs some time to get accustomed to, especially for learners with no prior knowledge of programming and data science. 

      Compared to other statistical analysis technologies, R poses a challenge because it requires a more thorough understanding of coding principles. As a programming language, it deviates from some standard conventions that Python or its counterparts often follow. For many learners integrating the realms of software development and data science may create difficulty.


      R comes with a massive collection of packages and test tools for the fast delivery of data analytics, visualization, and processing projects. As a language conceived by statisticians, it excels at statistical computing, predictive analytics, and data science. Like Python, R can scrape data from the web and subsequently cleanse and correct it. 

      Additionally, R is extremely robust when it comes to data visualization. It’s capable of creating virtually any type of custom graph, mainly thanks to its ggplot2 library. 


      One of R’s strongest qualities is the vast size of its package ecosystem. The language has gathered a vibrant community of active users, most of whom engage in data science and predictive analytics projects. Think of a use case, and there are high chances that a package supporting its delivery already exists. 

      Yet, because the scope of the language is rather limited, R has never entered the mainstream like Python. As a result, only about 5.7% of developers use R.

      The verdict

      While the Internet is teeming with speculations on R replacing Python or another way around, there is no reason why the two languages couldn’t peacefully coexist. R leans heavily into statistical models, while Python offers a broader approach to data manipulation. Programmers working on machine learning implementations are much more likely to go with Python. Non-programmers who need to conduct deep statistical analysis will probably choose R.

      Certainly, Python takes the cake for versatility. It supports all kinds of data formats and integrations and enables pulling data from the web. In contrast, R is limited to working with Excel, CVS, and text files and only allows basic web scraping. But all things considered, the two languages aren’t as much competing as they offer different benefits within the same, broadly defined area of data science.


      • Python tops the ranks for the ease-of-use, and development speed, and productivity.
      • It is one of the best languages for data science and analytics projects.
      • Like Ruby (and Ruby on Rails), Python is well-suited for rapid prototyping.
      • Compiled languages, like Java and C#, exceed Python in performance.
      • Python has one of the most powerful and active communities among all languages.

      07 The economy of Python development: how much does it cost?

      Here’s the part that will probably resonate with you the most – we’ll talk $$. If you ask: ‘How much will I pay for developing my Python project?’, we will tell you that there’s only one answer: ‘It depends.’ Coming up with a specific figure without knowing these details is impossible. 

      Python development cost can range from $3,000 for developing a small software modification and $80,000 for creating a medium-size web platform. For enterprise-grade systems, the figure can get much higher, exceeding $100,000.

      Multiple factors come into play when gauging any software development project's cost, regardless of the programming language. We explore them below. 

      Software development costs. The Python Advantage.

      Several intrinsic features of Python make it more cost-efficient than some other programming languages. These are, among others:

      • An extensive catalog of support libraries that speed up coding
      • Open licensing, which doesn’t require licenses fees
      • Extended support to 3rd party modules that streamlines integration
      • A large pool of developers, which facilitates access to talent
      • A robust community for faster, more efficient problem-solving
      • A user-friendly syntax that increases development speed
      • Multi-platform support for easier delivery across various platforms
      • Support for easy prototyping (the code is instantly executable)

      Python developers’ rates

      Python developers’ salaries sit in the mid-upper range compared to other languages. C#, C++, or Java developers tend to earn slightly less than their Python-speaking peers. However, the language gets nowhere near technologies with the highest earnings, such as Scala, Go, or Perl.

      • According to Stack Overflow’s survey, the median for professionals developing code in Python averages $59,000/year globally. 
      • In the USA, it’s considerably higher and stands at $120,000/year. These numbers are consistent with the data from other sources. 
      • Based on over 1,200 reported salaries, Indeed estimates that Python Developers' average salary in the USA (no breakdown into seniority) stands at $52,26/hour 
      • The top-grossing specialists live in San Francisco, followed by New York and San Jose. One of the lowest-paid Python Developers in the country can be found in Atlanta.
      • reports that the British Python experts get nearly $80,000/year, on average (with senior experts making up to $117,300/year), or $40,87/hour. Irish Python developers make quite similar money, the same as most of their French colleagues.
      • A German software developer expert with Python typically earns from $58,250/year to $65,000/year, depending on the source (PayScale and Glassdoor, accordingly). 
      • In Poland, the salary of Junior Python specialists averages at $13,850/year. Senior experts are worth nearly three times more. A Python professional with +10 years of experience can count on $38,600/year, on average (source: Bulldogjob).
      • As we travel East, the rates lower, with Python Developers in Ukraine getting from $10,500/year to $17,150/year (there are huge discrepancies in reported rates, depending on the sources). 
      • Traditionally, India-based specialists charge the lowest rates. The average base salary for a Python Developer in India ranges from $7,700/year to $8,300/year.
      • However, when we move to Shenzhen, China, the rates go back up. Junior Python Developers can count on $35,200/year, while Seniors make up to $62,500/year.

      6 tips for hiring Python developers who’ll deliver success

      If you’ve decided that Python is the best choice for your project needs, you might be wondering how to find experienced team members who’ll bring your software idea to fruition. Here’s something extra for you. We’ve prepared six skills apart from core knowledge of Python to look for in a reliable developer.

      Sticking to these guidelines will help you avoid wasting time and money on a second-rate Python team. 

      • A firm grasp of Python frameworks. The Python ecosystem is so vast that it’s impossible (and, quite frankly, needless) to be proficient with all frameworks and libraries. However, the person you want to hire should be well-acquainted with at least one of the leading Python frameworks, such as Django or Flask. Besides, they also should be familiar with more specialized tools that support Python development for specific scenarios, such as data analysis or visualization.
      • Familiarity with front-end. Experienced Python developers should also demonstrate an understanding of front-end technologies (including JavaScript, HTML, and CSS) for developing web applications.
      • Acquaintance with databases. No one expects Python developers to double up as database admins. However, a certain knowledge of different databases is essential. As developing most Python applications involves connecting with the underlying databases, you may expect a strong candidate to understand data models, be familiar with SQL, and have at least a basic understanding of Object Relational Mapping (ORM).
      • Knowledge of data science and ML algorithms. If your project has anything to do with automation, data analytics, cleansing, and visualization, or generation of data-driven insights, check your candidate’s grasp of the related frameworks and libraries.
      • Awareness of various project management methodologies. While there are hundreds of methodologies, most experienced developers will usually be familiar with the top three – Waterfall, Agile, and XP. The more they understand the principles of the approach adopted in your project, the faster their onboarding and smoother the work going forwards.
      • Efficient communication. At the times of ubiquitous remote teams, we don’t need to emphasize how crucial communication skills are to any project's success. Language fluency is one thing you should expect from your team members-to-be; responsiveness, curiosity, and communication efficiency are equally important.

      Pay attention to the above skills when reviewing candidates to join your Python project. And if you feel that looking for Python experts is too much hassle, turn to us. With our vast network of software talent, we’ll find specialists who’ll instantly get up to speed and consistently deliver work in line with your expectations.

      08 Python community – who, what, where, and how?

      09 Python in 2021 and beyond

      We hope that this report has been useful in establishing where Python stands now. But let’s pause for a moment and think about Python’s future.

      What is the future of the Python language?

      Already several generations old, Python has a bright future ahead. We’re going through the fourth industrial revolution now, when fields like robotics, automation, nanotechnology, smart healthcare, and other areas impacted by machine intelligence and data science are gaining significance. As computer science has become somewhat of an umbrella term, Python enjoys a comfortable lead as the most popular programming language of 2020. And that state is likely to continue. 

      The U.S. Bureau of Labor Statistics expects an increase in computer and information research jobs by 15% by 2029.

      The U.S. Bureau of Labor Statistics projects a pronounced growth in data science jobs in the coming years. According to the institution’s Occupational Outlook Handbook, the demand for computer and information research scientists will increase by 15% by 2029, much faster than the average for all occupations. The CareerFitter website anticipates even a stronger trend, foreseeing a 35% surge in demand for statisticians and mathematicians! The outlook for other jobs involving handling of data and working with AI and machine learning systems is equally optimistic.  

      According to the World Economic Forum, Python is a top-three skill for data scientists.

      The World Economic Forum’s Future of Jobs report lists Python programming among the top three skills for data and AI occupations. Python is an essential area of knowledge on the learning agenda for data science professionals. When it comes to engineering jobs, the language is considered the most in-demand technology, according to the study.  

      The world’s most progressive higher education institutions have Python programming classes in their curricula; this makes a strong case for the language’s bright prospects. Python was the most popular introductory teaching language at top-ranked US universities already a few years ago. Today, it retains its leading position, being taught in courses at such elite establishments as Harvard, Yale, Stanford, MIT in the USA, or Cambridge, Oxford, National University of Singapore, University of Tokyo, and University of Sydney if we look elsewhere.

      All in all, it is safe to comment that while new technologies are going to emerge, and some of the existing, like R, Swift, or Go, are likely to grow in importance, Python’s position will remain unchallenged in the next few years. The language will continue to dominate AI, machine learning, and data science programming, as well as web development. And who knows, maybe new fields of Python’s application will come to light in the upcoming years?
