python - 如何解析这个 JSON 字典以打印出键值对？

Question

cow = {
    "data": [
        {
            "id": "1179640025492630",
            "indicator": "google-analytics|UA-97996598-1",
            "type": "API_KEY"
        },
        {
            "id": "1469013519830038",
            "indicator": "google-analytics|UA-96613605-2",
            "type": "API_KEY"
        },
        {
            "id": "1459958767410551",
            "indicator": "google-analytics|UA-86399386-2",
            "type": "API_KEY"
        },
        {
            "id": "1507839102569000",
            "indicator": "google-analytics|UA-89570367-2",
            "type": "API_KEY"
        },
        {
            "id": "1276736575767341",
            "indicator": "google-analytics|UA-69774312-4",
            "type": "API_KEY"
        },
        {
            "id": "1292251910882451",
            "indicator": "google-analytics|UA-93952538-3",
            "type": "API_KEY"
        }
    ],
    "paging": {
        "cursors": {
            "after": "NQZDZD",
            "before": "MAZDZD"
        }
    }
}

我想从数据字典中提取“id”:“1179640025492630”。

我尝试使用 for 循环，例如:

for i in cow['data']:
    for key,value in i:
        if(i == 'id'):
            print key,value
        else:
            pass

它给了我一个值错误，例如:

Traceback (most recent call last):
  File "./dict.py", line 14, in <module>
    for key,value  in ['data']:
  ValueError: too many values to unpack

如果我使用.iteritems，我会得到一个AttributeError:

Traceback (most recent call last):
  File "./dict.py", line 14, in <module>
    for key,value   in ['data'].iteritems:
  AttributeError: 'list' object has no attribute 'iteritems'

Answer 1

如果您只想打印与 id 关联的所有值:

for thing in cow["data"]:
    print(thing["id"])

输出:

1179640025492630
1469013519830038
1459958767410551
1507839102569000
1276736575767341
1292251910882451
