Converting JSON objects in to dictionary in python
提问by Guruswamy B M
I have string of data basically which has a objects with in the objects..
我基本上有一串数据，其中有一个对象。
{"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
没有我的要求是将其转换为 JSON 对象作为字典。我试过以下方式
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...
但是 the_dict 只给出左边的值，没有右边的值......
In the same way if string has a format..
以同样的方式，如果字符串具有格式..
"[{"sample": false, "radop": null, "view": true, "Example1": null}, {"noMarket": false, "Example2": null}]"
and following the same code.
并遵循相同的代码。
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...
它给出了长度为 2 的字典，这就是预期的......
Can any please help me out in first case how can I get a dictionary...
任何人都可以在第一种情况下帮助我如何获得字典...

I found two errors in your first example:
我在你的第一个例子中发现了两个错误：
- You have a
groupin your stringified (Json) version of your dict. This should be a"group"(with quotes). - You misspelled your variable;
JSON_Datalist≠JSON_DataList(lowercase vs. capital L).
- 您
group的字符串化 (Json) 版本的 dict 中有一个。这应该是一个"group"（带引号）。 - 你拼错了你的变量；
JSON_Datalist≠JSON_DataList（小写与大写 L）。
After fixing both, I had no problems anymore:
修复两者后，我再也没有问题了：
>>> 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'}

I have figured out how to generate the_dict['user']['group']['id']dynamically through Python's evalexpression.
我已经弄清楚如何the_dict['user']['group']['id']通过Python的eval表达式动态生成。
Keysis the input from the user, separated by :. Example: user:group:id.
Keys是来自用户的输入，以 分隔:。例子：user:group:id。
CODE:
代码：
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

after fix the problem group should be "group", below code can meet your requirement
修复问题后组应该是“组”，下面的代码可以满足您的要求
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'}}}
