You should be subclassing `object`, but that's a minor point which
isn't the cause of your problem.

This creates a *local variable* named "z". You want an *attribute*
named "z", so you should be doing:
self.z = 1
instead. Same problem elsewhere; you must *always* explicitly use
`self` when referencing an attribute of the current object. Python !=
Java or C++.
Cheers,
Chris
