works. I have about 25 classes of drawn objects. for instance class linefromslope creates an instance of class line. One of my "ugly solutions" involves a class prop: within each class, put properties like slope and midpoint within the self.prop instance and making a copy of that. Would __deepcopy__ facilitate this? Or am I assuming too much: is __deepcopy__ just a method I invent to do what I want? -- http://mail.python.org/mailman/listinfo/python-list
