It's not horrible:

py> class A:
...     pass
...
py> class B:
...     pass
...
py> a = A()
py> a.__class__ == A
True
py> a.__class__ == B
False

Still, if you can use new-style classes, you should.

Also, you should probably Google for "duck typing".  Generally, in 
Python it is frowned upon to check the type of an object.  There are 
times when it's necessary, but if you're just starting off, my guess is 
that you haven't discovered one of these times yet...
