在Python中将JSON字符串列表转换为JSON数组

Question

将此列表包含两个JSON strings ：

myJSONStringList = ['{"user": "testuser", "data": {"version": 1, "timestamp": "2018-04-03T09:23:43.388Z"}, "group": "33"}',
'{"user": "otheruser", "data": {"version": 2, "timestamp": "2018-04-03T09:23:43.360Z", }, "group": "44"}']

如何将其转换为JSON数组？ 这是我想要的输出：

[{"user": "testuser", "data": {"version": 1, "timestamp": "2018-04-03T09:23:43.388Z"}, "group": "33"}, 
{"user": "otheruser", "data": {"version": 2, "timestamp": "2018-04-03T09:23:43.360Z", }, "group": "44"}]

我知道我可以通过执行myJSONStringList.replace("'", "")来做一个肮脏的解决方案，但是通过使用例如json模块，是否有任何pythonic解决方案？

提前致谢

Answer 1

将JSON字符串解码为dicts并将它们放入列表中，最后将列表转换为JSON

json_list = []
json_list.append(json.loads(JSON_STRING))
json.dumps(json_list)

或更多pythonic语法

output_list = json.dumps([json.loads(JSON_STRING) for JSON_STRING in JSON_STRING_LIST])

Answer 2

使用json.dumps之前json.loads将数据转换成字典对象这也有助于防止valueError: Expecting property name enclosed in double quotes 。

例如：

import json
myJSONStringList = ['{"user": "testuser", "data": {"version": 1, "timestamp": "2018-04-03T09:23:43.388Z"}, "group": "33"}',
'{"user": "otheruser", "data": {"version": 2, "timestamp": "2018-04-03T09:23:43.360Z", }, "group": "44"}']

print([json.loads(json.dumps(i)) for i in myJSONStringList])

输出：

[u'{"user": "testuser", "data": {"version": 1, "timestamp": "2018-04-03T09:23:43.388Z"}, "group": "33"}', u'{"user": "otheruser", "data": {"version": 2, "timestamp": "2018-04-03T09:23:43.360Z", }, "group": "44"}']
