How difficult would it be to implement a system in python that would warn if there are unnecessarily imported packages/modules/objects in the code? I mean that when developing some code one frequently imports stuff, deletes the import, changes stuff here and there, imports other stuff, later decides to change things and consequently delete the line with the import, etc, etc. As a result there can stay packages/modules/objects that are in the end not used. It would be great if python would issue a warning once the program finishes.
Style-checkers will help with this. pylint, pychecker, and pyflakes are all good tools. I tend to use pyflakes most often. It's small and doesn't do as much as the others, but it does unused imports and undefined name checks much faster than the others. I can run it compulsively on my file.
