I'm not sure to understand what you want exactly. A concrete example would probably help. But from what I understood, you could just use a thin wrapper like: _marker = object() class Accessor(object): def __init__(self, obj, name): self._obj = obj self._name = name def __call__(self, new_val=_marker): if new_val is _marker: return getattr(self._obj, self._name) else: setattr(self._obj, self._name, new_val) class Foo(object): def __init__(self, bar, baak=42): self.bar = bar self.baak = baak foo = Foo('allo') bar = Accessor(foo, 'bar') assert bar() == foo.bar == 'allo' bar(42) assert bar() == foo.bar == 42 If that doesn't answer your question, please pardon my stupidity and provide some more concrete example. -- http://mail.python.org/mailman/listinfo/python-list
