You could be using a class as class generator. Like (in some off the cuff code :)

class gen(object):
    class base_1(object): pass
    ...
    class base_n(object): pass

    def __init__(self, ...):
        ...
    def mk_cls(self, ..., type):
        '''makes a class based on the type passed in, the current state of
           the class, and the other inputs to the method'''

I feel like when you need this functionality it will be very clear to you. If you don't need to be doing something similar than it probably isn't a good use case.
