Chapter 9 Tutorial for Classes Not Working

[Tom Grove]

Here is my version:

Python 2.4.3 (#2, May  9 2006, 21:56:54)
[GCC 3.4.4 [FreeBSD] 20050518] on freebsd6

I am trying the classes example from the tutorial because some other 
class related stuff I am doing is not working either.

Straight from Chapter 9:

class MyClass:
    "A simple example class"
    i = 12345
    def f(self):
        return 'hello world'


 From here I run:
    x = MyClass
    xf = x.f
    while True:
       print xf()

This gives the following error:

Traceback (most recent call last):
  File "<stdin>", line 2, in ?
TypeError: unbound method f() must be called with MyClass instance as 
first argument (got nothing instead)

Please help...this is killing me!
