The choice of a programming language for a future project is one of the most important decisions a manager has to make. It affects the cost of development, safety, and stability of the product, feasibility to scale when sales are up, and so on. Every language has a team of passionate adepts, and the competition between them often reminds religious wars.


In this blog post, we would like to compare two of the most popular general-purpose, object-oriented programming languages: Python and C#. Both languages are surrounded by stereotypes. To draw a more realistic picture of how both Python and C# look like, let’s study some facts and data about each language.

What Is Python?

Designed in 1991, Python is an interpreted programming language with a strong level of abstraction. Python’s development project started in 1989 by Guido van Rossum for whom it was just a ‘hobby’ enterprise for entertainment during the Christmas holidays. Such a lightness in attitude towards programming became the characteristic feature of Python. Since the language has one of the easiest to learn syntaxes, it became super-popular among the beginning programmers and people, who are not engaged in coding full-time, like academic scholars. 

What Is C#?

C# is an object-oriented, multi-paradigm, type-safe programming language. Contrary to Python, which was initially a garage enterprise, C# was designed in the office of a major software company, Microsoft, by Anders Hejlsberg. It was built to satisfy the increasing demands for web applications that C++ and Visual Basic(VB) couldn’t meet. While developing a new coding system, Hejlsberg drew inspiration from such languages as C++, Java, and Object Pascal. Because of its compiled nature, C# is one of the fastest languages available on the market. The most popular C# framework is .NET. Development with C# requires additional tools: Visual Studio .NET, Far, and Redgate .NET Reflector.

Why Should We Compare Python and C#?

Although Python and C# are quite different in terms of syntax and language design, both languages are used in the same spheres: machine learning, back-end development, design of mobile applications, web applications, desktop software, and so on. Despite Python and C# being general-purpose languages, each of them has its own domain where it shines at its best. To understand better what are the most efficient application strategies for both languages let’s compare Python vs C#. Criteria to evaluate will be the popularity of the language, size and amity of the community, easiness of coding, performance, safety, a pool of available talents, and cost of development.


An important factor to keep in mind while choosing a technology for your product is the approval of the language among the professional community. The high popularity of the programming language indicates that the technology is reliable and trustworthy, while the decrease of interest in language signifies that in a short time there will be a need to switch.


According to one of the most prestigious ratings, TIOBE Index, both Python and C# used to be close competitors for the hearts of the audience and held an almost equal share of search-request. The situation in Python vs C# the contest changed dramatically in 2018 when Python significantly gained in popularity. Julia Silge, the data scientist at Stack Overflow, claims that such a shift is correlated with a wide explosion of AI, machine learning, and data science by an enterprise.

The success of the language depends much on the efforts of the community that invents new features, develops code packages and libraries, identifies and eliminates vulnerabilities.


Because of its huge popularity, Python has one of the biggest communities on the web. For example, there are over 2100 contributors on Github who develop Python’s framework Django and over 1600 people who work on CPython. With joint efforts, those people and many-many others created over 137,000 libraries available for download. Python’s community is very friendly and helpful. Analytics company SlashData ranks Python’s community of developers as the second-best in the world. The ranking of C# is lower, although still pretty decent. For two years in a row between 2017 and 2019 C# kept the top-four position.

Easiness of coding

The simplicity of a code is an important characteristic to consider since it influences the quality of the final product. Clumsy code is hard to debug and secure, while the clean and well-structured program is easy to maintain for newcomers. As was written in Structure and Interpretation of Computer Programs, the textbook of programming taught at MIT:


Python vs C# - testimonial 1


In general, Python appears to be an easier programming language to work with than C#. According to Coursera, it will take you from two to six months to learn the fundamentals of Python, while C# requires much more effort - from six to twelve months.


To get a better idea of how Python and C# work, let’s have a look at the ‘Hello, World’ program written in both languages.


Python vs C# hello world


As you have witnessed, comparing Python to C#, the first one has a much simpler syntax than the other. It requires only 1 line to create a ‘Hello, World’ program with Python, while it will take eight lines to write a program with C#.

Talking about performance, C# overcomes Python with a great advantage. To prove that C# runs programs faster with less memory usage, let’s look at data about bench-mark program execution. 


Python vs C# - table 2

As you may see, C# executes programs much faster than Python. Is it a good reason to choose C# as a primary technology for the product? The answer depends on how important high performance is important for your software. Laurence Tratt, Professor of Software Development at King's College London,
states that in the majority of cases, the difference in language’s performance has no impact on the functionality of the software. The power of modern computers is so great that most programs run fast enough, even with the slowest language implementations.

2020, the year of the global pandemic and large-scale switch to remote work, was also a year of cyber-crime flourishing. According to Sophos’ The State of Ransomware 2021 survey, 51% of organizations were hit by ransomware. The cost of such attacks is high. The average security bill paid by small and medium businesses was $170,404. For this reason, it is forecasted that safety standards for software in the coming years will be strict as never before. 


The reliability of a product may be enhanced by the wise choice of programming languages. Old, tested by time and community languages, like C# and Python, appear to be more certain than new languages like Go or Rust. According to WhiteSource, Python shares the smallest part of reported open-source vulnerabilities - only 6%. The most common vulnerabilities are CWE-20 (Improper Input Validation), CWE-264 (malfunction of permissions, privileges, and access control), and CWE-79 (improper neutralization of input during web page generation).

Talent pool

Recruitment of a professional, well-trained developer may sometimes be challenging. Fortunately, plenty of programmers are familiar with both Python and C#. According to Slash Data, there were around 7 million Python developers in the world in 2018, while the number of people who code with C# reached 6,2 million. The other data source, a survey conducted by Stack Overflow, demonstrates that 41.6% of all developers know how to work with Python and 32.3% how to work with C#.

Cost of development

Clever budget planning is as important as the design of features and services. Even the greatest ideas are limited by the number of resources, both financial and time, available. Both Python and C# belong to one of the cheapest technologies to develop with. According to the StackOverflow Developer survey 2020, the median salary of Python engineers reached $59k per year vs $57k for engineers who work with C#. Since Python operates with a syntax close to a natural language, development with this language is quicker and requires less time. For this reason, Python is a perfect solution for start-up companies that are still testing their product.

  • Development of desktop applications. Unsurprisingly, a language designed and supported by Microsoft is the best tool to create software for Windows. The list of the software created with C# includes Paint.NET, Windows Installer XML, Microsoft Visual Studio, Open Dental, and many others.
  • Development of enterprise applications. The main benefit of C# is its agility for customization. For this reason, the language is a great choice for software with specific and unique requirements. That software includes automated billing systems, payment processing, customer relationship management (CRM), call center and customer support, etc. Contact us to hire a team of experienced C# developers.
  • Web development. Although the web is conquered by Python, there are plenty of successful companies that use C#. One of the examples is StackOverflow. A great advantage of applications written with C# is a convenient integration with Microsoft’s Azure cloud.
  • Development of mobile applications. Since C# is compatible with Microsoft Visual Studio, it is a convenient tool for creating cross-platform mobile applications that run on Android, iOS, and Windows devices. A framework for the development of mobile apps with C# is Xamarin. A bright example of such cross-platform development is the online card game Hearthstone. 
  • Development of search engines. As you may know, Microsoft owns its own web search platform, - Bing. Although it is not as popular as Google or Baidu (Bing shares only 2.32% of the worldwide desktop search engine market), it is still a good example of an enterprise-scale application processing enormous data.
  • Game development. One of the most popular game engines, - Unity, is built with C#. The runtime is based on C++ while Unity Scripting API depends on C#.
