@adbar HI can you check this PR and merge it if it doesnt need any further changes

Hi @mohmmadAyesh, I don't exactly understand what your PR does, in any case it does not fix #134, e.g. by adding a requirements-dev.txt file.

It provide a github action check the formatting code style using black package if it doesnt fix #134 please tell me what require from me to fix it

I added a github workflow that check coding style using black package when a new PR is opened

I updated the description in #134, please follow the steps indicated there if you want to draft a pull request.

Black is already part of the CI/CD on Github workflows so the current PR doesn't fix anything IMO.
