我想将上面的 JSON 转换为 python 中的字典数据类型。在上面的脚本中，我想读取这个值 -

{"Domain":"UDE","Intention":"Unspecified"}

我是json新手，所以我无法理解。有人可以给我一些建议吗？

【问题讨论】：

那么你尝试了什么？还有什么你不明白的？
你试过使用内置的json module吗？
我试过这个：json.loads("nlu_classification")。但它不起作用

标签： python json python-2.7 python-3.x dictionary

【解决方案1】：

只需使用 python 自带的 json 模块。

import json
json_string = '{"first_name": "Guido", "last_name":"Rossum"}'
parsed_json = json.loads(json_string)
print(parsed_json['first_name'])
"Guido"

参考：http://docs.python-guide.org/en/latest/scenarios/json/

【讨论】：

你能告诉我如何读取其中的域和意图值吗？
非常简单。像使用任何普通字典一样使用它。
