Re: Can you create an instance of a subclass with an existing instance of the base class?

With new-style classes you can find out a class' subclasses and then you can instantiate the subclass you want. Suppose you have two classes A and B, B is a subclass of A, A is a new-style class. Now you have an A's instance called "a", to instance B you can do the following: b = a.__class__.__sub
