  Not guaranteed, but this should be good enough:

------------------------------------------------------------------------
class FinalClass:
    def __init__(self):
        if self.__class__ is not FinalClass:
            raise SomeError, "you can't subclass from me!"
------------------------------------------------------------------------

  Whether or not this is a good idea is another thing.
