Not really:
>>> class chatty(object):
... def __init__(self): self.__dict__['__hide'] = {}
... def __setattr__(self, name, value):
... print 'sa', name, value
... self.__dict__['__hide'][name] = value
... def __getattr__(self, name):
... print 'ga', name
... return self.__dict__['__hide'].get(name)
...
>>> c = chatty()
>>> x = c.zop = 23
sa zop 23
>>>
As you can see, there is no read-access to c.zop, which plays the role
of y there.
