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

same sort of style as the past answer - but in fewer lines :P

import os,sys
parentdir = os.path.dirname(__file__)
sys.path.insert(0,parentdir)

file returns the location you are working in
