Python 解析字典中的字典列表以检索特定键'；每个字典中的值

我得到了一个JSON响应，并使用

JSON.loads（）

将其转换为python字典。因此，字典如下所示：

{u'body': u'[{"id":"1","entity":"zone","status":"PROCESSING","url":null,"createdOn":"2019-10-11T05:49:11Z"},{"id":"2","entity":"floor","status":"FAILED","url":null,"createdOn":"2019-10-11T05:49:15Z"},{"id":"3","entityType":"apartment","status":"SUCCESS","url":null,"createdOn":"2019-10-11T05:49:18Z"}]',u'isBase64Encoded': False, u'statusCode': 200}

我将其命名为

testStatusList

。我想检索

“body”

中每个字典的

“status”

键的值。我能够通过给出

body=testStatusList['body']

来检索

“body”

。现在，字典看起来像：

[
    {
        "id": "1",
        "entityType": "zone",
        "status": "PROCESSING",
        "url": null,
        "createdOn": "2019-03-07T12:47:10Z"
    },
    {
        "id": "2",
        "entityType": "floor",
        "status": "FAILED",
        "url": null,
        "createdOn": "2019-08-19T16:46:13Z"
    },
    {
        "id": "3",
        "entityType": "apartment",
        "status": "SUCCESS",
        "url": null,
        "createdOn": "2019-08-19T16:46:13Z"
    }
]

我尝试过这个解决方案[

但我一直在获取

AttributeError:“unicode”对象没有属性“items”

。是否有其他方法获取unicode对象的项

因此，我基本上希望检索所有状态，即PROCESSING、FAILED和SUCCESS，以便在某个特定“id”出现故障时设置“if”条件以显示适当的消息。我对我的方法非常不确定，因为我对Python一无所知。任何帮助都将不胜感激！谢谢！

正文仍然是（unicode）顶部blob中的字符串。使用

json。再次在该字符串上加载
：

body = """[
    {
        "id": "1",
        "entityType": "zone",
        "status": "PROCESSING",
        "url": null,
        "createdOn": "2019-03-07T12:47:10Z"
    },
    {
        "id": "2",
        "entityType": "floor",
        "status": "FAILED",
        "url": null,
        "createdOn": "2019-08-19T16:46:13Z"
    },
    {
        "id": "3",
        "entityType": "apartment",
        "status": "SUCCESS",
        "url": null,
        "createdOn": "2019-08-19T16:46:13Z"
    }
]"""


import json
body = json.loads(body)
status =[]
for b in body:
   for k,v in b.items():
       if k == 'status':
           status.append(v) 
print(status)

结果:

[‘处理’、‘失败’、‘成功’]

好吧，这对我来说很有效！我不知道我得再装一次尸体。谢谢！
