字典根据key或者value排序

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)]
