Python program examples

[Eugene Kelly]

I am looking for neat little examples of Python programs for an intro.
programming course I am currently giving to business students. We are
working in a MS Windows 98 environment. If you have any examples to hand
that you would be willing to share please send them to me directly.
Programs should be small i.e. < 100 lines max and < 50 would be best.
Thanks in advance,
Eugene.
