No, its not. Only inside of it. And the question really is: why? If you need a class that can be instantiated regardless of the execution of f, make it a globally visible class. If it depends on something f computes, make it a function-local one (if you like) Diez -- http://mail.python.org/mailman/listinfo/python-list
