3-4 字典的嵌套

1、字典的嵌套

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、嵌套字典的取值

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、嵌套字典的增删改查--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     '乔美玲':{
 7         "bag":['xx','lv',],
 8         "house":['三环','4环'],
 9         "hzp":['skii','ysl'],
10         'language':{
11             '普通话':10,
12             '东北话':20,
13             '日语':0,
14             '英语':4
15         }
16     }
17 }
18 car_nums = d['春波']['car'].values()
19 
20 
21 # 1、春波卖了一套上海的房子，卖了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，买了一辆劳斯莱斯
29 d['春波']['money']=d['春波']['money']-10000
30 d['春波']['car'].append('劳斯莱斯')
31 
32 # 4、乔美玲的东北话退步了， 从20级变成了10级
33 d['乔美玲']['language']['东北话']=10
34 
35 # 5、乔美玲会哪些语言
36 print(d['乔美玲']['language'].keys())
37 
38 # 2、算一下马春波有多少辆车
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)
45 print(d)
