python: get directory two levels up

Question

Ok...I dont know where module x is, but I know that I need to get the path to the directory two levels up.

So, is there a more elegant way to do:

Answer 1

Personally, I find that using the os module is the easiest method as outlined below. If you are only going up one level, replace ('../..') with ('..').

    import os
    os.chdir('../..')

--Check:
    os.getcwd()
