Re: Populating a dictionary, fast

Not sure if it would make a difference, and it would imply re-
organizing your preceding lines, but what about doing the dictionary
build in one go, rather than incrementally? Using the dict function,
which takes a list of (key,value) tuples. I use it frequently as a
space-saver and it works well enough. It may speed things up, I
dunno. I had to break out your formatting in its own function and
that can't help too much.

Something like:

def fmt(line):
id,name = line.strip().split(':')
id = long(id)
return (id,name)

id2name = dict([fmt(line) for line in
iter(open('id2name.txt').readline,'')])

Cheers
