Short answer: don't use __slots__ until you're comfortable writing
metaclasses and decorators. __slots__ are a performance hack strictly
for advance

Hello,
consider this code
>>> class A(object):
... def __init__(self):
... self.a = 1
... self.b = 2
...
>>> class B(A):
... __slots__ = ["x","y"]
...
>>> b=B()
>>> b.a
1
>>> b.b
2
>>> b.x = 100
>>> b.y = 100
>>> b.z = 100
no exception here
does __slots__
