如何打印python模块层次结构？

Question

I have a file which is dynamically loaded. Because of the dynamic loading, I have no idea what its module path is, and all of my best guesses (per the filesystem structure) have failed so far.

1. How do I inspect the full module path from within the running file?
2. How do I walk the hierarchy programmatically?

(Python 2.6)

Answer 1

If you're able to import that module runtime anyways you have the access to __file__ attribute of it, which will give you the exact location of your module.

for example:

In [1]: import os

In [2]: print os.path.dirname(os.__file__)
/usr/lib/python2.7
