python - 在 Python 中遍历嵌套字典和子字典

Question

JSON:

data = {"result":[{"name":"Teddy","list":{"0":"24","1":"43","2":"56"}},
           {"name":"Barney","list":{"0":"24","1":"43","2":"56"}]}

代码:

i = 0
j = 0
for p in data['result']:
    print('Name: ' + p['name'])
    for v in p['list']:
        i += 1
        print("{0} : {1}".format(i,v[j]))
        j += 1

我试图访问每个值并将它们打印出来，但不幸的是，没有任何成功，任何帮助表示赞赏。

我见过: Loop through all nested dictionary values?

从您的尝试看来，您想要做的是以下内容:

data = {"result":[
    {"name":"Teddy","list":{"0":"24","1":"43","2":"56"}},
    {"name":"Barney","list":{"0":"24","1":"43","2":"56"}}]}

for p in data['result']:
    print('Name: ' + p['name'])
    for k, v in p['list'].items():
        print("{0} : {1}".format(k,v))

请注意 data不是 JSON 对象，而是 Python 字典。

输出:

Name: Teddy
1 : 43
0 : 24
2 : 56
Name: Barney
1 : 43
0 : 24
2 : 56
