As developer or first time contributor; getting started with project (understating code) is so hard when there is codes that do not follow PEP8, while contribution guide states it is followed.

In my opinion, we need to first fix all PEP8 issues in phase manner (because some style error such as E501 needs thoughtful change) and finally use PyPI packages like pycodestyle / flake8 / {{black }}in CI/CD checks.
