In the new (2.4) version of the Tutorial, that statement has been
removed.  What you're using has been called "old-style" classes for
quite a while now (since 2.0?).  Any new Python code should really be
using the "new-style" classes (inherit from "object" and use things
like "super".

But FWIW, it appears to still work with Python 2.4:

#---------- <snip FILE="Foo.py"> -----------------
class Foo:
    def foo(self):
        print "foo"

class Bar(Foo):
    def foo(self):
        print "bar"
        Foo.foo(self)
#----------- </snip> ------------


# Now in the Python interpreter:

>>> from Foo import *
>>> f = Foo()
>>> f.foo()
foo
>>> b = Bar()
>>> b.foo()
bar
foo

So nothing jumps out to me that you did obviously wrong, sorry.  But
in general my advice would be to switch to using "new-style" classes.
