Add a python linting testing for our repository

It is very important to keep the coding style of the whole codebase to be consistent through all the team members because it will help us to read the code more easily.

To be added to the CI.

Start by locating the repository's CI configuration and checking how Python checks currently run. Define the linting check there and confirm that the CI reports style failures; the issue does not name a specific configuration file, linter, or test to run.
