json格式的数据在python中表现为字符串str类型的数据

import json


def json_to_dict(my_json: str) -> dict:
    return json.loads(my_json)


def dict_to_json(my_dict: dict) -> str:
    return json.dumps(my_dict)


if __name__ == '__main__':
    my_dict = {
        'name': "小明",
        "age": 12,
    }
    my_json = dict_to_json(my_dict)
    print("json格式数据：", my_json)
    my_dict_from_json = json_to_dict(my_json)
    print("dict格式数据：", my_dict_from_json)
