使用 python 從 JSON output 中提取字段

Question

使用 Python，如何將字段 RestartRowID 提取到變量中？：

{
  "emp": [
     {

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

就像是：

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

謝謝..

Answer 1

將 json 數據轉換為字典

data_dict=json.loads(<jsondata>)

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

Answer 2

像這樣的東西：

>>> 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處於同一級別，因此您應該從另一個中提取一個。

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'
