I have modules at two different locations

e.g 

Location1
   |- com
       |-__init__.py
       |-foo1
          |-__init__.py
          |-bar1.py

Location2
   |- com
       |-__init__.py
       |-foo2
          |-__init__.py
          |-bar2.py

The two locations are in the PYTHONPATH, in the above order. When I try to import com.foo2.bar2, I get the following error:

Traceback (most recent call last):
  File "", line 1, in 
ImportError: No module named foo2

If I change the top-level package name to com2 (i.e location2/com2/foo2/bar2.py), then the import statement succeeds.

I think I am doing something incorrect, could someone please help?

Thanks.

    What you want is called namespace packages in Python. One way to do them with the standard library is to use pkgutil; another way is to use the third-party module pkg_resources provided by the distribute or setuptools projects.

    Support for namespace packages will be improved in the standard library and interpreter with PEP 382.
