Python: How can I know which package I am importing?

Question

I would like to have this info during run-time or in ipython. For example,

import matplotlib

How do I know which matplotlib.py is used if I have multiple versions or I just want to know where the file located.

Thanks

I think you actually want to look for `__version__`, but I don't know if it's defined for matplotlib. — Rik Poggi, Mar 09 '12 at 22:53

Inspect the module's __file__ attribute.

In [1]: import matplotlib

In [2]: matplotlib.__file__
Out[2]: '/usr/lib/pymodules/python2.7/matplotlib/__init__.pyc'

(Works in vanilla Python too.)

You can even just type `matplotlib`, giving you `` – Thomas K Mar 10 '12 at 16:42

You can use the sys.modules to find the path of it.

Such as:

import math
import sys
print sys.modules['math']
