So why did you define it with only one formal parameter?

As you can see, your email program thoroughly messed up this source
code. Please send your messages in text form, as html frequently gets
trashed as it goes through various gateways. This is a text-mailing list.

Why do you ask the user for the input, when it was already supplied as a
parameter? it's best practice to separate input from calculation, and
your teacher had done that in his/her specification.

Presumably you should be returning the centered/swapped string.
No idea where the following break is supposed to happen. But once you
eliminate the raw_input, you'll be eliminating the while True and the break.
