Because it only works in classic classes due to a bug in descriptor handling:
>>> class C(object):
@property
def eggs(self):
print 'in eggs'
self.eggs = 7
return self.eggs
>>> c=C()
>>> c.eggs
in eggs
Traceback (most recent call last):
File "<pyshell#12>", line 1, in -toplevel-
c.eggs
File "<pyshell#10>", line 4, in eggs
self.eggs = 7
AttributeError: can't set attribute
