解析嵌套字典

Question

b={   'cricket': {   'Arts & Entertainment': [{'id': '6003760631113'},
{'id': '6003350271605'},
{'id': '6003106646578'},
{'id': '6003252371486'},
{'id': '6003370637135'}]},
'News, Media & Publications': [   {'id': '6003020834693'},
{'id': '6003139266461'},
{'id': '6003716669862'},
{'id': '6002971085794'},
{'id': '6003172932634'}]
}

如何解析这个嵌套字典，以便检索这个嵌套列表中的所有id ?

我已经试过了:

for j in b['cricket']:
print(j)

给了我这样的结果:-

艺术,娱乐

然后我试了这个:

for j in b['cricket']:
for k in j:
print(k['id'])

给了我这个错误:-误差

Answer 1

ids = [int(row['id']) for row in b['cricket']['Arts & Entertainment']]

会给你一个数字列表，

[6003760631113, 6003350271605, 6003106646578, 6003252371486, 6003370637135]

和你的新编辑;

ids = [int(row['id']) for row in b['cricket']['Arts & Entertainment'] + b['News, Media & Publications']]

Answer 2

试试这个

for i in b['cricket']['Arts & Entertainment']:
print(i['id'])

6003760631113
6003350271605
6003106646578
6003252371486
6003370637135
