1、字典的巢狀

1 stu_info = {
2     'xiaoming':{"password":123456,'phone':132323,'age':18,'addr':'北京'},
3     'xiaohei':{'password':123456,'phone':1223423,'age':18,'addr':'上海'}
4 }

2、巢狀字典的取值

1 stu_info = {
2     'xiaoming':{"password":123456,'phone':132323,'age':18,'addr':'北京'},
3     'xiaohei
 
':{'password':123456,'phone':1223423,'age':18,'addr':'上海'}
4 }
5 print(stu_info['xiaoming']['phone'])

3、巢狀字典的增刪改查--案例

 1 d = {
 2     '春波':{
 3         "car":{'BMW':5,'BENZ':3,'audi':3,'byd':4},
 4         "house":["北京",'南京','上海'],
 5         "money":1000000,},
 6     '喬美玲':{
 7         "bag
 
":['xx','lv',],
 8         "house":['三環','4環'],
 9         "hzp":['skii','ysl'],
10         'language':{
11             '普通話':10,
12             '東北話':20,
13             '日語':0,
14             '英語':4
15         }
16     }
17 }
18 car_nums = d['春波']['car'].values()
19 
20 
21 # 1、春波賣了一套上海的房子，賣了500w
22 d['春波
 
']['house'].pop(-1)
23 d['春波']['house'].remove('上海')
24 d['春波']['money']=d['春波']['money']+5000000
25 d['春波']['money']+=5000000
26 
27 
28 # 3、春波花了100w，買了一輛勞斯萊斯
29 d['春波']['money']=d['春波']['money']-10000
30 d['春波']['car'].append('勞斯萊斯')
31 
32 # 4、喬美玲的東北話退步了， 從20級變成了10級
33 d['喬美玲']['language']['東北話']=10
34 
35 # 5、喬美玲會哪些語言
36 print(d['喬美玲']['language'].keys())
37 
38 # 2、算一下馬春波有多少輛車
39 print(car_nums)
40 print(sum(car_nums))
41 sum = 0
42 for n in car_nums:
43     sum = n + sum
44 print(sum)
