How to apply relative directory in python when imported from different module?

Question

Here's the problem:

In package main.A, there's a module AM and a config.ini file. In AM, I'm using ./config.ini to refer to this file. This just works fine.

Whereas in package main.B, there's another module named BM, which imports main.A.AM module. In this time, it throws that config.ini cannot be found in /main/B/

Could anyone tell me how to import this relatively located file in Main.A? Thanks a lot!

The __file__ magic variable stores the path to the file it appears in.

If you put the following line in main.A, it will always point to a file residing in the same directory as main.A, regardless of the location main.A is imported from:

import os.path as osp 
osp.join(osp.dirname(__file__), 'config.ini')
