It doesn't look like you're reading the section on classes: http://docs.python.org/tutorial/classes.html You create a class like this: class MyClass(MySuperclass1, MySuperclass2): # class attributes and methods attr = 3 def method(self): print self.attr You can instantiate it by calling the class, as if it were a function: myinstance = MyClass() You call a method getting the method (myinstance.method), and then calling that as if it were a function. myinstance.method() Polymorphism is "duck typed" -- that is, it's based on the presence/absence of attributes and methods, not on declared interfaces (Python has no interfaces). So, for example, "foo.read()" works on any object bound to the name "foo", as long as it has a read method that takes no parameters. This could be a file-like object, but it could also be something completely different that just happens to have a method by the same name. > Is there a previous discussion in the group that I could read.
