Classes in modules

I'm trying to get this source code split into multiple files:

http://pygermanwhist.googlecode.com/files/pygermanwhist.12.py

I've been trying to make  so that I have one class per file for easier
readability.  My problem is that the interpreter keeps saying that it
can't find methods and so forth whenever I try to split the code up.

This has been a recurring problem for me in languages such as C++ and
Java.  I'm used to programming in C.
