How to find where a function was imported from in Python?

Instead of

from bar import *

use

from bar import foo

Using the from ... import * syntax is a bad programming style precisely because it makes it hard to know where elements of your namespace come from.

foo.__module__ should return bar

If you need more info, you can get it from sys.modules['bar'], its __file__ and __package__ attributes may be interesting.

Try this:

help(foo.func_name)
