The SetName class method sets the name on the *class* dictionary. The class's __init__ method also sets a name (None) on the *instance* dictionary. From an instance's perspective, the instance dictionary will shadow the class dictionary. If you remove the attribute from the instance dictionary entirely (delete the "self.name = None" line), and leave the class dictionary as is, then you will get the output you want (although from your later post I am not certain that this is the behaviour you want).

Right. > The idea was to use @setname instead of instance.SetName(instance.__name__). The appropriate place to do this so that it applies to all instances of the class rather than to the class would be inside the __init__ method. Also, instances don't have a __name__ attribute, so it's still unclear to me what you're looking for. Did you mean the effect to be that of "instance.SetName(cls.__name__)"? If so, then the decorator approach (with the line "self.name = None" removed) should be fine for your purposes -- you'll just have the name stored in the class dict instead of in each instance dict, but it will still be visible as long as you haven't shadowed it. -- http://mail.python.org/mailman/listinfo/python-list
