从Python的collections库文档:>>> from collections import OrderedDict>>> # regular unsorted dictionary>>> d = {'banana': 3, 'apple':4, 'pear': 1, 'orange': 2}>>> # dictionary sorted by key -- OrderedDict(sorted(d.items()) also works>>> OrderedDict(sorted(d.items(), key=lambda t: t[0]))OrderedDict([('apple', 4), ('banana', 3), ('orange', 2), ('pear', 1)])>>> # dictionary sorted by value>>> OrderedDict(sorted(d.items(), key=lambda t: t[1]))OrderedDict([('pear', 1), ('orange', 2), ('banana', 3), ('apple', 4)])>>> # dictionary sorted by length of the key string>>> OrderedDict(sorted(d.items(), key=lambda t: len(t[0])))OrderedDict([('pear', 1), ('apple', 4), ('orange', 2), ('banana', 3)])
