I like this short tutorial http://hetland.org/python/instant-hacking if
you browse down the page there is a section called "Bigger Programs -
Abstraction" that deals with defining functions. Below that it goes
further in to functions.

Basicly a function needs to be defined and then called e.g.:

>>> def square(x):
    print x*x


>>> square(5)
25
>>> square(2.5)
6.25
>>> square(-3)
9
