I bet even one that did nothing more than a regex search for matched import statements would be good enough.

Zope 3 has an import checker that uses the compiler package and AST tree to check for unused imports. It seems like a better approach than a simple regex search.

http://svn.zope.org/Zope3/trunk/utilities/importchecker.py?rev=25177&view=auto The importorder tool uses the tokenizer module to order import statements. http://svn.zope.org/Zope3/trunk/utilities/importorder.py?rev=25177&view=auto Both are written by Jim Fulton. Ah, but does it run against Python 3? If so then this is something to suggest on python-mentor for someone to get their feet wet for contributing.

A possible alternative is the sfood-checker tool given here http://furius.ca/snakefood/ which I stumbled across whilst looking for something completely different.
