Did anyone read the chapter 3 of course notes? There seems to be a mistake in the codes in 3.5.5, P85:
...
def SubclassOfFoo(Foo):
def bar(self, arg):
Foo.bar(self, arg)

...

I think it should be "class SubclassOfFoo(Foo):", as function doesn't have a self.
Do I wrong?

Yes, I agree with you.  With the subclass we are adding or overriding a method of the class Foo.  So we have to define a new subclass of Foo:   class SubClassOfFoo(Foo).

Definig a new function as it is defined in the notes we are using the class as parameter, but we arn't using the inheritance property of the subclasses.
