Importing modules from parent folder

Question

I am running Python 2.5.

This is my folder tree:

ptdraft/
  nib.py
  simulations/
    life/
      life.py

(I also have __init

Answer 1

You can use OS depending path in "module search path" which is listed in sys.path . So you can easily add parent directory like following

import sys
sys.path.insert(0,'..')

If you want to add parent-parent directory,

sys.path.insert(0,'../..')

This works both in python 2 and 3.
