It would have been simpler to just test: >>> class Ghost(object): ... def __init__(self, name): ... self.name = name ... say = "whoo" ... def greetings(self): ... print "%s from %s %s" \ ... %(self.say, self.__class__.__name__, self.name) ... >>> g1 = Ghost("Albert") >>> g2 = Ghost("Ivan") >>> g1.greetings() whoo from Ghost Albert >>> del Ghost >>> g1.greetings() whoo from Ghost Albert >>> g1.__class__ <class '__main__.Ghost'> >>> the del statement remove a name from the current namespace. period.
