This suggests that there is an order to the numbers on your ticket
(you want to print them out in the same order), but not to the winning
numbers, which are simply a set. The easiest way to handle that would
be to iterate over your numbers, asking "if number in
winning_numbers:", and printing out a "match" marker if it is or a
"non-match" marker if it isn't.
