Question

I have this:

dictionary = { (month, year) : [int, int, int] }

I’d like to get a list of tuples/lists with the ordered data(by month and year):

#example info
list = [(8,2010,2,5,3),(1,2011,6,7,8)...]

I’ve tried several times but I can’t get to a solution.

Thanks for your help.

Don’t use as your identifier built-in names — that’s a horrible practice, without any advantages, and it will land you in some peculiar misbehavior eventually. So I’m calling the result thelist (an arbitrary, anodyne, just fine identifier), not list (shadowing a built-in).

import operator

thelist = sorted((my + tuple(v) for my, v in dictionary.iteritems()),
                 key = operator.itemgetter(1, 0))
