error in tutorial for 3.0, section 9.3.3

[Vincent Davis]

Section 9.3.3 says that given,
class MyClass:
    """A simple example class"""
    i = 12345
    def f(self):
        return 'hello world'

and x = MyClass()
then this

x.counter = 1
while x.counter < 10:
    x.counter = x.counter * 2
print(x.counter)
del x.counter

will print 16

http://docs.python.org/3.0/tutorial/classes.html#a-first-look-at-classes

I am reading this section so to learn about classes but if this is right I
think I need to start over.


Thanks
