Python：计数模块导入？

Question

I am a mid end python developer at an animation studio, and have been presented with a unique diagnostics request ;

To assess what code gets used and what doesn't.

Within the sprawling disorganized structure of Python modules importing modules : I need to count the python modules that are imported, and possibly at a deeper level, find which methods are called.

As far as finding out which methods are called, I think that would be easy to solve by writing my own logging metaclass.

However, I'm at loss to imagine how I should count or log module imports at varying depths.

Thanks for any ideas you may have.

If you have a way to exercise the code, you can run the code under coverage.py . It's normally used for testing, but its basic function would work here: it indicates what lines of code are run and what are not.
