Python has no notion of a partial class because it is a pure compile time construct. You might merge different class definitions by means of a meta class that puts everything together but whether or not certain methods in the merged class are available depends on which modules are imported. This might give rise to a "virtual" or runtime module. It is not a module that refers to a physical file on the disc but is a pure runtime construct. When creating this module all physical modules that define class fragments might be put together by means of the metaclass mechanism. I indeed used this construction to unify different access points before I reimplemented it using partial classes in C# which are very fine IMO. -- http://mail.python.org/mailman/listinfo/python-list
