It may be used to make various applications as it isn't tailored for any particular issue. Its adaptability and beginner-friendliness have elevated it to the top of the list of programming languages today. 


Often, developers fall in love with Python due to its enhanced productivity. The edit-test-debug cycle is rapid because there is no compilation phase. Python programs are simple to debug since a segmentation failure is never caused by a bug or incorrect input. Instead, the interpreter raises an exception when it finds a mistake, and the interpreter produces a stack trace if the application doesn't catch the exception.


A source-level debugger allows you to inspect local and global variables. Plus, it lets you evaluate arbitrary expressions, create breakpoints, and walk through code one line at a time. The debugger is developed in Python, showing the language's analytical capability. 


Besides, adding a few print statements to the source code is the fastest way to debug a program. And the short edit-test-debug cycle makes this basic technique quite successful.

How to Get Started with Python for Finances

Python is a popular programming language for finance because it has a large number of useful libraries for analyzing and manipulating data, as well as for implementing machine learning algorithms. Some of the most commonly used libraries for finance include NumPy, Pandas, and scikit-learn.


To use Python for finance, you must install the necessary libraries on your system. You can install it using the pip package manager, which is included with most Python installations.


After installing the libraries, you can start using Python for finance by loading and analyzing financial data, such as stock prices or financial statements. For example, you can use the Pandas library to load a CSV file containing historical stock data and then use the NumPy library to perform calculations on the data, such as calculating moving averages or generating trading signals.


Additionally, you can use Python to build and train machine learning models for finance, such as using scikit-learn to build a model that can predict stock price movements based on historical data. The models can help create trading strategies or analyze a portfolio's performance.


Overall, Python is a valuable language for finance. With the correct libraries and tools, it can be used to carry out various tasks, from data analysis and visualization to machine learning and algorithmic trading.


Now, I will walk you through some terrific hands-on activities to help you get started with Python for finance. Please note you need basic knowledge of Python to be able to perform this activity.

1. Import Python Libraries

First, you must install the Python libraries that you will be using. The library is a set of techniques and functions that enable you to execute various tasks.

2. Obtain The Data

Second, you must collect all of your transaction data. You can export your transaction data from online banking into a CSV file. But most banks allow you to do this from their app.


If you have many bank accounts or can't retrieve your transaction data from your online banking, use Yolt. With this software, you can access all your accounts in one location and quickly download a CSV file including all of your transactions (within the app, head to the More tab, Privacy Settings, and then tap on Download your information).


Because you want it to be accessible to everyone, irrespective of your financial institution or app, the CSV file you'll use should only have six columns. These entail ID, date, amount, description, merchant, and category. You may even add as many as you like. After this has been done, you are to convert your transaction data to a Pandas DataFrame.

3. Manipulate the Data and Customize the categories for your transactions

Implementing this step allows you to change your data and choose how you wish to handle your transactions. You may remove all rows having a specified string in a specific column with the easy line. Then, repeat the command as many times as you want to remove other rows. After that, define your transaction categories. 

After choosing all the transaction groups, you wish to use to manage your finances, find and categorize transactions incorrectly labeled in the DataFrame. This is critical in shaping your final report to best meet your needs.

One method is to identify the rows that contain a given string and assign them to a specific category. For instance, all the rows containing Uber, Zipcar, or Bird should go under the transport category.

4. Draft Your Monthly Report

Step 3 should result in a clean DataFrame with transactions aggregated by the categories that make the most sense to you. Then you are ready to create your monthly report, including three separate charts.

  • Net Worth Over Time Chart

The first chart shows how your Net Worth (Income minus Expenses) changes over time. You can add a column to retrieve the transaction's year and month to create a monthly report. To make the first graph, group the DataFrame by the year-month column you just generated and add a row with the total sums. You can generate a line graph using Net Worth on the Y-axis and Date on the X-axis using the Plotly Go Library.

  • Monthly Expenses Chart

The second chart will illustrate how your spending changes month after month. This will allow us to see if your monthly expenditure exceeds your budget and compare it to past months. Again group the DataFrame by the year-month column, but only after you've deleted all the transactions labeled as income.


Using the Plotly Express Library, you can generate a bar chart using Expenses on the Y-axis and Dates on the X-axis.

  • Expenses Breakdown Chart

The final chart will show how we spent our funds by breaking it into the categories we identified in Step 3. To do this, we will pivot our DataFrame to get the total costs for a specific month and category. Consequently, we'll make another basic line chart with Expenses on the Y-axis and Dates on the X-axis.

5. Create the Final Dashboard

Now that you've generated three distinct charts displaying your net worth, monthly expenses, and their breakdown, the next step is to integrate them into a single Dash App that will operate on your local laptop.
