You can use the __file__ attribute of a module:
In [9]: csv.__file__

For a function use the __module__ attribute to get the module:
In [10]: csv.reader.__module__
Out[10]: '_csv'

This is a string so you have to do a little more work to get the file:

In [12]: import sys
In [13]: sys.modules[csv.reader.__module__].__file__
