Others have told you that at a and b belong to the class object rather then
to the instance objects.  Perhaps this will demonstrate the difference:

>>> class foo():
...     def __init__(self):
...             self.a = 0
...             self.b = 0
...
>>> c1 = foo()
>>> c1.a = 5
>>> c2 = foo()
>>> print c2.a
0
