Do you mean this: >>> class A(object): pass ... >>> class A(object): ... colour = 'red' ... >>> a = A() >>> def getcolour(self): ... print self.colour >>> A.myAttribute = getcolour >>> a.myAttribute() 'red' Of course, this is why python's is called dynamic language: the ability to change a class' definition on runtime, even on an already instantiated objects. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
