I reported a problem with PyLint not knowing that __doc__ is indeed an attribute of a function. So I tried to go through and find out where PyLint makes that determination, between its own code and Astroid code.
Is there a roadmap showing where to look for the determination that a particular member is present in a function?
I want to develop a patch to fix my problem, I do.
I think you need to install pylint in your virtual env? If you are using pylint when developing then technically it's a development dependency and should be marked as such in your pipfile/requirements file.
