Python 字典插入多级值

Question

我想转换以下字典：

dict_ = {'/xxx/xxx': 
         {'Price': '460.000','Location': 'France'},
'/yyy/yyy': {'Price': '360.000','Location': 'Germany'},
'/fff/ff': {'Price': '149.000','Location': 'Russia'},
'/aaa/aaa': {'Price': '150.000','Location': 'UK'}}
print(dict_)

想添加一个日期级别，如图：

dict_ = {'/xxx/xxx':{'2022/01/28':{'Price': '460.000','Location': 'France'}},
        '/yyy/yyy': {'2022/01/28' :{'Price': '360.000','Location': 'Germany'}},
        '/fff/ff':  {'2022/01/28': {'Price': '149.000','Location': 'Russia'}},
        '/aaa/aaa': {'2022/01/28': {'Price': '150.000','Location': 'UK'}}}

以及添加日期的第二个选项如下：

dict_ = {'2022/01/28' : {'/xxx/xxx': 
         {'Price': '460.000','Location': 'France'},
'/yyy/yyy': {'Price': '360.000','Location': 'Germany'},
'/fff/ff': {'Price': '149.000','Location': 'Russia'},
'/aaa/aaa': {'Price': '150.000','Location': 'UK'}}}

谢谢

Answer 1

dict_ = {
    '/xxx/xxx': {'Price': '460.000','Location': 'France'},
    '/yyy/yyy': {'Price': '360.000','Location': 'Germany'},
    '/fff/ff': {'Price': '149.000','Location': 'Russia'},
    '/aaa/aaa': {'Price': '150.000','Location': 'UK'}
}
print(dict_)

date='2022/01/28'
d2={}
d3={date:{}}
for key, value in dict_.items():
    d2[key] = {date:value}
    d3[date][key]=value

print('first option')
print(d2)
print('second option')
print(d3)

d2 的结果

{'/xxx/xxx': {'2022/01/28': {'Price': '460.000', 'Location': 'France'}},
 '/yyy/yyy': {'2022/01/28': {'Price': '360.000', 'Location': 'Germany'}},
 '/fff/ff': {'2022/01/28': {'Price': '149.000', 'Location': 'Russia'}},
 '/aaa/aaa': {'2022/01/28': {'Price': '150.000', 'Location': 'UK'}}}

d3 的结果

{'2022/01/28': {'/xxx/xxx': {'Price': '460.000', 'Location': 'France'},
  '/yyy/yyy': {'Price': '360.000', 'Location': 'Germany'},
  '/fff/ff': {'Price': '149.000', 'Location': 'Russia'},
  '/aaa/aaa': {'Price': '150.000', 'Location': 'UK'}}}
