Getting file path of imported module

Question

How can I get the file path of a module imported in python. I am using Linux (if it matters).

Eg: if I am in my home dir and import a module, it should return back the full path of my home directory.

Answer 1

This will give you the directory the module is in:

import foo
os.path.dirname(foo.__file__)

Answer 2

Modules and packages have a __file__ attribute that has its path information. If the module was imported relative to current working directory, you'll probably want to get its absolute path.

import os.path
import my_module

print os.path.abspath(my_module.__file__)

Answer 3

I've been using this:

import inspect
import os
class DummyClass: pass
print os.path.dirname(os.path.abspath(inspect.getsourcefile(DummyClass))

(Edit: This is a "where am I" function - it returns the directory containing the current module. I'm not quite sure if that's what you want).

Answer 4

To find the load path of modules already loaded:

>>> import sys
>>> sys.modules['os']
<module 'os' from 'c:\Python26\lib\os.pyc'>
