字典排序是python里比较常用的方法，在此作下总结。
按键排序
>>> test_dict
{1: ‘a‘, 2: ‘b‘, 3: ‘c‘, 4: ‘d‘} >>> key_sort=sorted(test_dict.iteritems(), key=lambda key:key[0], reverse = False) >>> key_sort [(1, ‘a‘), (2, ‘b‘), (3, ‘c‘), (4, ‘d‘)] >>> key_sort=sorted(test_dict.iteritems(), key=lambda key:key[0], reverse = True) >>> key_sort [(4, ‘d‘), (3, ‘c‘), (2, ‘b‘), (1, ‘a‘)] >>> test_dict {1: ‘a‘, 2: ‘b‘, 3: ‘c‘, 4: ‘d‘}
按值排序
>>> value_sort=sorted(test_dict.iteritems(), key=lambda value:value[1], reverse = True) >>> value_sort [(4, ‘d‘), (3, ‘c‘), (2, ‘b‘), (1, ‘a‘)]
