Let's you have a Python dictionary and you want to get a representation of it sorted by the value.

Method 1:

`>>> xs = {'a': 4, 'b': 3, 'c': 2, 'd': 1} >>> sorted(xs.items(), key=lambda x: x[1])[('d', 1), ('c', 2), ('b', 3), ('a', 4)]`

Method 2:

`>>> xs = {'a': 4, 'b': 3, 'c': 2, 'd': 1} >>> import operator>>> sorted(xs.items(), key=operator.itemgetter(1))[('d', 1), ('c', 2), ('b', 3), ('a', 4)]`
