That looks to me like the best solution to the OP's specific
question. It's amazing how many cool things are tucked into the
standard library. While it's easy to miss these things, I appreciate
the effort to keep Python's core relatively small. (Not knowing about
itemgetter, I would have gone with the list comprehension.)
