reduce namespace pollution in python scripts

Question

I am working on some old python code and I was wondering if there is an easy way to find out which modules are imported but never used. I have a few hundred python scripts, each importing tens of modules (most scripts where copy-pasted by some template).

This is normally the job of a *linter* tool. [Flake8](https://pypi.org/project/flake8/) would certainly deserve a try. — Serge Ballesta, Oct 19 '20 at 08:49

Pylint can do this. It reports "Unused import <module>" (warning named unused-import, code W0611).

This warning is enabled by default along with many others, but if you want to check for this warning specifically, you can do:

pylint --disable=all --enable=unused-import *.py

Using Pycharm does inform you if any modules or variables are used or not. That would be good for you in my opinion as an IDE.
