Just happened to read this thread and wanted to say this is a neat
little example-- thank you! I have a couple of followup questions.
(1) Is there a performance penalty for using key=operator.attrgetter()?
(2) The Player class looks like a nice model for a data table when one
wants to sort by arbitrary column. Would you agree?
(3) Suppose one wished to construct a player list from a collection of
attribute lists, e.g.,
names = ['bob', 'sam', 'linda']
attack = [7, 5, 8]
defense = [6, 8, 6]
# construct players list here
Can you recommend an efficient way to construct the player list?
Thanks!
Marcus
