OT: Python Import question

[Jeremy Wilkins]

Hi,

I've been trying to tell one python script to import another, the
problem is the other script is in a different non-child folder.
Neither are in the default import path. I can't set PYTHONPATH before
hand and when i set it inside a script it seems to have no effect, eg

import os
os.environ['PYTHONPATH'] = '/folder/containing/secondscript'
import script2

I'm stumped so any help much appreciated

thanks
