JSON 可以将 JavaScript 对象中表示的一组数据转换为字符串,然后就可以在函数之间轻松地传递这个字符串,或者在异步应用程序中将字符串从 Web 客户机传递给服务器端程序. 2. JSON语法 数据在键值对中 数据由逗号分隔 花括号保存对象 方括号保存数组 3. json常用的方法 JSON到字典转化: ret_dict = json.loads(jso...
You can access the actual dictionary directly byaccessing 0thitems from the list. Let’s see the example now. importjson StudentDict = {"id":22,"name":"Emma"} MarksList = [StudentDict,78,56,85,67]# SerializationencodedJson = json.dumps(MarksList, indent=4)# Deserializationdata = json...
