Which version of python are you using?

I think random.shuffle was added in 2.0 or 2.1

If you are still using 1.5 or 1.6 I would definitely recommend
upgrading, especially if you are just starting to learn. There
are a lot of great new features that it would be good to learn
right from the start (just look how much simpler this example
becomes with the new method ;o)

Try this:

dir([])

That will show you most of the list methods.
