Looks like there's a missing 2. ?

Anyway, this might help:

>>> class Spam:
...  pass
...
>>> class Eggs(Spam):
...  pass
...
>>> spam = Spam()
>>> eggs = Eggs()
>>> isinstance(spam, Spam)
1
>>> isinstance(spam, Eggs)
0
>>> isinstance(eggs, Spam)
1
>>> issubclass(spam.__class__, eggs.__class__)
0
>>> issubclass(eggs.__class__, spam.__class__)
1
>>> eggs.__class__ == Spam
0
>>> eggs.__class__ == Eggs
1
>>>
