I'm having trouble sorting a dictionary based on values when the values are all lists, and i want to sort the list by key with the largest value lists in decreasing size.
Currently, I have the following: from operator import itemgetter dict = {'A': [(10, 20), (12, 18), (5, 11), (18, 25)], 'C': [(1, 200)], 'B': [(1, 10), (100, 200), (150, 300), (250, 350), (300, 400)], 'D': [(3, 400)]} I have tried several methods, and seem to have come closest using: sorted(self.dict.items(), key=itemgetter(1), reverse=True) My problem is that this will return the key order A,D,C,B The order I want is based on the size of the lists each key points to: B,A,D,C or B,A,C,D Question: itemgetter(1) is just returning the value, which is a list. How do I specify that I want the values to be sorted by list size? Thanks! john -- "We are healthy only to the extent that our ideas are humane." --Killgore Trout
