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__ nothing when used in derived classes?
class Z(object): .... __slots__ = ["x","y"]
.... z=Z()
z.x = 100
z.y = 100
z.z = 100 Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'Z' object has no attribute 'z'
here it works like expected
