python嵌套字典的用法

注意，嵌套中是list还是dict

例子：嵌套中是字典

d = {
    '春波':{
        "car":{'BMW':5,'BENZ':3,'audi':3,'byd':4},
        "house":["北京",'南京','上海'],
        "money":1000000,},
    '美玲':{
        "bag":['xx','lv',],
        "house":['三环','4环'],
        "hzp":['skii','ysl'],
        'language':{
            '普通话':10,
            '东北话':20,
            '日语':0,
            '英语':4
        }
    }
}


#1、春波卖了一套上海的房子，卖了500w
d['春波']['house'].pop(-1)
d['春波']['money']+=5000000
print(d)

#2、算一下春波有多少辆车
car_num=d['春波']['car'].values()
print(sum(car_num))
#或者
sum=0
for n in car_num:
    sum=n+sum
    print(sum)

#3、春波花了100w，买了一辆劳斯莱斯,卖掉之前的奥迪
d['春波']['car'].pop('audi')
d['春波']['car']['LSLS']=3
d['春波']['money']-=1000000
print(d)

#4、美玲的东北话退步了， 从20级变成了10级
d['美玲']['language']['东北话']=10
print(d)

#5、美玲会哪些语言
language_s=d['美玲']['language'].keys()
print(language_s)

嵌套中是list

d ={'春波':{'car':['BMW','ben-z','qq'],'house':['beijing','shanghai','nanjing','深圳'],'money':100000},
    '乔美玲':{'bag':['lv','coach','pd'],'house':['ss','ssd','sddf'],
          'language':{'普通话':10,'dongbaihua':20,'riyu':0,'yingyu':4}}}

d['春波']['car'].append('laosilaisi')  #增加一辆laosilaisi
d['春波']['house'].pop(-1)  #卖掉深圳的房子
d['春波']['house'].remove('nanjing') #卖掉
d['春波']['money'] = d['春波']['money'] + 5000000   #增加
print(d)
