How to Write Unit Tests for Python Functions

This guide will help you get started with unit testing in Python. You'll learn how to use Python's built-in unittest module to set up and run unit tests and write test cases to test Python functions. We'll start by defining a Python function and write unit tests to check if it works as expected. There are four test methods, each checking for a specific input. For arguments of other types, you can use type hinting to enforce types and raise exceptions as needed.
