使用 python 从 JSON output 中提取字段

Question

使用 Python，如何将字段 RestartRowID 提取到变量中？：

{
  "emp": [
     {

      "id": "",
      "company": "y",
      "address": "y",
      "mobile no": 0,
      "name": 0
    }
  ],
  "RestartRowID": "0x0000000000133a09"
}

就像是：

id = emp["RestartRowID"]
print (id)

谢谢..

Answer 1

将 json 数据转换为字典

data_dict=json.loads(<jsondata>)

您可以使用 data_dict['RestartRowID'] 获得所需的答案

Answer 2

像这样的东西：

>>> import json
>>> a = '''{
...   "emp": [
...      {
... 
...       "id": "",
...       "company": "y",
...       "address": "y",
...       "mobile no": 0,
...       "name": 0
...     }
...   ],
...   "RestartRowID": "0x0000000000133a09"
... }'''
>>> data = json.loads(a)
>>> data['RestartRowID']
u'0x0000000000133a09'
>>> 

Answer 3

emp和RestartRowID处于同一级别，因此您应该从另一个中提取一个。

data = {
  "emp": [
     {

      "id": "",
      "company": "y",
      "address": "y",
      "mobile no": 0,
      "name": 0
    }
  ],
  "RestartRowID": "0x0000000000133a09"
}

Output：

In [264]: id = data["RestartRowID"]

In [265]: id
Out[265]: '0x0000000000133a09'
