We have been using https://pep8speaks.com/ — a GitHub integration.
Works pretty well for reporting PEP transgressions.

Another approach is the one taken by Napari, which is to automatically
run Black to format every contribution.  The only disadvantage is that
you need developers to install a pre-commit hook which, in their case,
they do using the pre-commit package:
