python -- import module in same directory

Question

I have a project setup like this (tell me if it's wrong):

 project/
     module_1/
         __init__.py
         foo.py
     module_2/
         __init__.py
         bar.py

In foo.py:

from module_2 import bar

I get:

ImportError: No module named module_2

However, if I change my project setup to this:

 project/
     module_1/
         __init__.py
         foo.py
         module_2/
             __init__.py
             bar.py

it works. How do I fix this?

Thanks

Yeah -- it happens whether the import statement is in module_one/foo.py or module_one/__init__.py — Walrus the Cat, Sep 22 '14 at 18:14
Because module2 is one step up while you are in foo. You are supposed to write ../module2 import bar. Note the ../ — lmc, Sep 22 '14 at 18:15
there's no __init__.py in my top directory. should there be? — Walrus the Cat, Sep 22 '14 at 18:22

Try a relative import:

from ..module_2 import bar

Then you refer to it as just bar: bar.method().

EDIT: add a __main__.py to project and run it from one level up, with

python -m project

it gives the "attempted relative import from another package" error – Walrus the Cat Sep 22 '14 at 18:22
