This is usually known as a Singleton.
If you only want it to store values, or use "normal" methods, the 
most direct way is a simple module - modules are already singletons in Python.
If you want to include properties, descriptors, and such, look for 
the Singleton (or Borg) pattern in the Python Cookbook:
