Re: [Zope3-Users] Utility for removing unneeded import statements
Hello Hermann, Z3 has an importchecker: Import checker This utility finds unused imports in Python modules. Its output is grep-like and thus emacs-friendly. ...

When I refactor code, I often have to restart zope3 over and over, only due to missing import statements. I have a quick-and-dirty python script that does exactly this. It cannot handle the new Zope import style which is import somepackage.somesubpackage from somepackage import otherpackage import somepackage.otherpackage.othersubpackage x = somepackage.somepackage.somevar y = otherpackage.othersubpackage.othervar and which I don't personally use.

Can the import checker in Z3 handle this? I don't think so. As I remember it did not find all unnecessary imports, that's why I switched to pyflakes. By pyflakes doesn't handle I meant it found too many unnecessary imports, some of which were actually very necessary (for the doctests). Marius Gedminas -- Linux is not user-friendly.
