Mapping module imports in Python for easy refactoring

Question

I have a bunch of Python modules I want to clean up, reorganize and refactor (there\'s some duplicate code, some unused code ...), and I\'m wondering if there\'s a tool to make

Answer 1

Python's modulefinder does this. It is quite easy to write a script that will turn this information into an import graph (which you can render with e.g. graphviz): here's a clear explanation. There's also snakefood which does all the work for you (and using ASTs, too!)

You might want to look into pylint or pychecker for more general maintenance tasks.
