pandac.PandaModules not found

I went in comand controls to open a demo on helloworld
and I put ppython helloworld.py like I’m suposed to and it said pandac.PandaModules not found
How do I open this file?

We need a bit more information to track this problem down.

Do any of the other sample Python applications work?

Does pview work?

Did you have already another version of Python installed before you installed Panda?

Can you show us the exact text it says before it complains about pandac.PandaModules?
