Yes it does:
>>> class A(object):
... aa = "aa"
...
>>> class B(A):pass
...
>>> B.aa
'aa

Use instead:
b = property(A.get_a, A.s

Right. That was what I should have said,

Looking at this interactive session:
>>> class A(object):
def __init__(self, a):
self.a = a
def get_a(self): return self.__a
def set_a(self, new_a): self.__a = new_a
a = property(get_a, set_a)
>>> class B(A):
b = property(get_a, set_a)
