Answer 1

You need an ordered data type to represent the sorted values (probably a list of tuples) as it's not possible to sort a directory because they are orderless whereas list and tuples aren't. Ex. import operator y = {2: 3, 4: 5, 5: 4, 3: 2, 1: 1} sorted_y = sorted(y.items(), key=operator.itemgetter(1)) A list of tuples, here sorted_x will be sorted by first element in each tuple dict(sorted_y) == y If you want to sort the keys instead of values, use import operator y = {2: 3, 4: 5, 5: 4, 3: 2, 1: 1} sorted_y = sorted(y.items(), key=operator.itemgetter(1)) Hope this helps.
