例：
根据value值排序
hasd = { ‘a‘: 12, ‘c‘: 7, ‘d‘: 17, ‘m‘: -9 } demo_dict = sorted(hasd.items(),key=lambda x:x[1]) print(demo_dict)
[(‘m‘, -9), (‘c‘, 7), (‘a‘, 12), (‘d‘, 17)]
根据key排序
hasd = {
‘a‘: 12,
‘c‘: 7,
‘d‘: 17,
‘m‘: -9
}
s = sorted(hasd.items(),key=lambda x:x[0])
print(demo_dict)
[(‘a‘, 12), (‘c‘, 7), (‘d‘, 17), (‘m‘, -9)]
