class A:
class __metaclass__(type):
_shared = 42
def get_shared(self):
return self.__class__._shared
def set_shared(self, value):
print "%r --> %r" % (self._shared, value)
self.__class__._shared = value
shared = property(get_shared, set_shared)
def get_shared(self):
return self.__class__.shared
def set_shared(self, value):
self.__class__.shared = value
shared = property(get_shared, set_shared)
Does that what you want?
