如何从python中的json文件的特定键获取字段和值

Question

I am trying to return the fields and values of a specific key but getting error Here is the sample json format:

"results": [
    {
      "time": "00:00",
      "app_name": "dcg",
      "avg": "7717"
    },
    {
      "time": "00:00",
      "app_name": "pds",
      "avg": "75.40223463687151"
    },
    {
      "time": "00:00",
      "app_name": "rdts",
      "avg": "1481.5555555555557"
    },
    {
      "time": "00:00",
      "app_name": "slbl",
      "avg": "786"
    },
    {
      "time": "01:00",
      "app_name": "pds",
      "avg": "36.4765625"
    }

here is my code

import json

json_data=open("some.json")
jdata = json.load(json_data)

for k, v in jdata.results.items():
    for k1, v1 in v.items():
        print(k1)
            print(v1)

Please note results is key and time field having multiple entries with same value.

Answer 1

Apart from fixing the broken indent, you can try the following. results is a key of your dictionary whose value can be accessed as jdata["results"] .

for v in jdata["results"]:
    for k1, v1 in v.items():
        print(k1)
        print(v1)

EDIT : To store them in a list, you can do

result = []

for v in jdata["results"]:
    for k1, v1 in v.items():
        result.append({"k1":v1})

[{'k1': '00:00'},
 {'k1': 'dcg'},
 {'k1': '7717'},
 {'k1': '00:00'},
 {'k1': 'pds'},
 {'k1': '75.40223463687151'},
 {'k1': '00:00'},
 {'k1': 'rdts'},
 {'k1': '1481.5555555555557'},
 {'k1': '00:00'},
 {'k1': 'slbl'},
 {'k1': '786'},
 {'k1': '01:00'},
 {'k1': 'pds'},
 {'k1': '36.4765625'}]        

Answer 2

I had to put your JSON in a containing set of brackets {} otherwise the JSON processor can't parse it....

ie..

{ 'result' : [...] }
