There's a lot of OOP Python code out there (in the Python libs too), so
it's hard to point out anything specific. Here's an example which I think
clearly illustrates OOP and inheritance at a very simple level:

Hm... I think it's best to start small really. If you don't understand OOP,
staring at the Zope codebase won't be a lot of help I presume. IMO you'd be
better off coding something small and simple instead. If the example with
polygons is too small, try extending it and make a CAD-like storage system
which can store all kinds of different shapes and calculate areas,
circumferences, etc. You'd need a point class, a polygon class (with all
kinds of subclasses), etc.
Or a Jukebox-like application (for ease of use without actually having it
produce sound) which can manage Collections of different types of Songs
(MP3, OGG, MIDI) and play random Songs from all Collections, or random
songs witin a Collection. The Jukebox itself could be a Collection of
