Given a bunch of objects that all have a certain property, I'd like to
accumulate the totals of how many of the objects property is a certain
value. Here's a more intelligible example:
Users all have one favorite food. Let's create a dictionary of
favorite foods as the keys and how many people have that food as their
favorite as the value.
d = {}
for person in People:
fav_food = person.fav_food
if d.has_key(fav_food):
d[fav_food] = d[fav_food] + 1
else:
d[fav_food] = 1
d ends up being something like: {'pie': 400, 'pizza': 200, 'burgers':
100} if 400 people like pie, 200 like pizza and 100 like burgers.
There's nothing wrong (that I know of) by doing it as I have up there,
but is there a simpler, easier way? Looking forward to hearing about
how much of a n00b I am. Thanks in advance!
