二、字典循环
1 #-*-coding:utf-8-*-
2 s = {
3 "id": 315,
4 "name": "矿泉水",
5 "sex": "女",
6 "age": 27,
7 "addr": "上海",
8 "grade": "摩羯座",
9 "phone": "18317155664",
10 "gold": 100
11 }
12 #第一种取字典key,value （效率高）
13 # for i in s: #直接循环字典，每次取的是字典里面的key
14 # print(i,s[i])
15 #
16
17 #第二种取字典key,value
18 # for key,value in s.items(): #直接循环字典，每次取的是字典里面的key
19 # print(key,value)
