Howto change Pythonpath in Python 3

I am trying to switch from using Python 2.6.5 to using Python 3.2a2. I am using OSX 10.6.4. However, when I open Idle in the Python 3.2a2 folder it cannot import any of the modules I installed to Python 2.6.5. Is there a way that I can share the s开发者_如何转开发ame folders on Python 3.2a2 ?

Python 2 and Python 3 are sufficiently different that you cannot in general share modules between them. You will need new, Python-3-compatible modules instead of re-using the Python 2 ones.

(It's possible with a great deal of care to make scripts that will work in both, but it's not usually the done thing. Python 3 was designed to be the big syntax compatibility breaking version.)
