7.2.1: Reverse sort of list.

Sort short_names in reverse alphabetic order. Sample output from given program:

['Tod', 'Sam', 'Joe', 'Jan', 'Ann']

short_names = ['Jan', 'Sam', 'Ann', 'Joe', 'Tod']

I understand to do a reverse list, as: short_names.reverse() . However, I am not certain how to type this code to produce an alphabetic order.
