在python中将JSON对象转换为字典

Question

I have string of data basically which has a objects with in the objects..

{"id":"XXXX", "name": "xyz", "user" : { "id": "XXXX", "username":"XYZ", group:{"id": "XXXX"}}}. You can check this format using "http://chris.photobooks.com/json/default.html" site.

No my requirement is to convert this to JSON objects as a dictionary. I have tried below way

import json
JSON_Datalist = '{"id":"XXXX", "name": "xyz", "user" : { "id": "XXXX", "username":"XYZ", group:{"id": "XXXX"}}}'
the_dict = json.loads(JSON_DataList)

but the_dict gives only left side values, no right values...

In the same way if string has a format..

"[{"sample": false, "radop": null, "view": true, "Example1": null}, {"noMarket": false, "Example2": null}]"

and following the same code.

JSON_Datalist = '[{"sample": false, "radop": null, "view": true, "Example1": null}, {"noMarket": false, "Example2": null}]'

the_dict = json.loads(JSON_DataList)

it gives the dictionary of length of 2, and this is what expected...

Can any please help me out in first case how can I get a dictionary...

Answer 1

I found two errors in your first example:

1. You have a group in your stringified (Json) version of your dict. This should be a "group" (with quotes).
2. You misspelled your variable; JSON_Datalist ≠ JSON_DataList (lowercase vs. capital L).

After fixing both, I had no problems anymore:

>>> JSON_Datalist = '{"id":"XXXX", "name": "xyz", "user" : { "id": "XXXX", "username":"XYZ", "group":{"id": "XXXX"}}}'
>>> the_dict = json.loads(JSON_Datalist)
>>> the_dict
{u'user': {u'username': u'XYZ', u'group': {u'id': u'XXXX'}, u'id': u'XXXX'}, u'id': u'XXXX', u'name': u'xyz'}

Answer 2

after fix the problem group should be "group", below code can meet your requirement

json_data={"id":"XXXX", "name": "xyz", "user" : { "id": "XXXX", "username":"XYZ", "group":{"id": "XXXX"}}}
data = json.dumps(json_data)
json_to_python = json.loads(data)
print (json_to_python)


{'id': 'XXXX', 'name': 'xyz', 'user': {'id': 'XXXX', 'username': 'XYZ', 'group': {'id': 'XXXX'}}}

Answer 3

I have figured out how to generate the_dict['user']['group']['id'] dynamically through Python's eval expression.

Keys is the input from the user, separated by : . Example: user:group:id .

CODE:

RefCount = 0
RespDict = json.loads(JSON_Datalist.content) #convert strings to Java object using JSON
SplitKeys = Keys.split(":") 
KeyCount = len(SplitKeys)
CommandText = "RespDict" #To setup command line based on keys information
while (RefCount <KeyCount):
    CommandText = CommandText+"['"+SplitKeys[RefCount]+"']"
    RefCount = RefCount + 1
    print CommandText        
print eval(CommandText)  #Final key value
