Define "doesn't see to work".

There's nothing wrong with super() in Python 2. You just have to 
understand what you're doing. It's still the right solution for doing  
inheritance the right way.

(Of course it doesn't exist in Python 1, so if Rick is still using Python 
1.5, that's a good excuse not to use super().)

The trick is to use new-style classes that inherit from object, and avoid 
the old-style classes that don't:

# Good
class Spam(object):
    ...

# Not so good
class Spam:
    ...

Ah yes, simple concepts like being unable to get super() working in 
Python 2. Good one Rick.
