In a language with strict types, you may need to make a set of classes all inherit from one base class simply in order to get the code to compile. A common example is a set of classes that all behave like file streams. You don't need to do this in Python. Simply have the object provide the right methods and you are done. -- Neil Cerutti -- http://mail.python.org/mailman/listinfo/python-list
