Why Use Python Assert Statement?

In Python, the assert statement is a potent debugging tool that can assist in identifying mistakes and ensuring that your code is operating as intended. Here are several justifications for using assert:

1. Debugging: Assumptions made by your code can be verified with the assert statement. You may rapidly find mistakes and debug your program by placing assert statements throughout your code.
2. Documentation: The use of assert statements in your code might act as documentation. Assert statements make it simpler for others to understand and work with your code since they explicitly describe the assumptions that your code is making.
3. Testing: In order to ensure that certain requirements are met, assert statements are frequently used in unit testing. You can make sure that your code is working properly and that any changes you make don’t damage current functionality by incorporating assert statements in your tests.
4. Security: You can use assert to check that program inputs comply with requirements and validate them. By doing so, security flaws like buffer overflows and SQL injection attacks may be avoided.

Python Assertions in any programming language are the debugging tools that help in the smooth flow of code. Assertions are mainly assumptions that a programmer knows or always wants to be true and hence puts them in code so that failure of these doesn’t allow the code to execute further.
