JSON(JavaScript Object Notation)是一种轻量级的数据交换格式。
它基于ECMAScript的一个子集，易于阅读和编写。 成都创新互联公司坚持“要么做到，要么别承诺”的工作理念，服务领域包括：成都网站制作、网站设计、外贸网站建设、企业官网、英文网站、手机端网站、网站推广等服务，满足客户于互联网时代的温宿网站设计、移动媒体设计的需求，帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴！ Python3 中可以使用json模块来对JSON数据进行编码。 |
d1 = [{"id" : 1,"name" : "Number1","age" : 11},{"id" : 2,"name" : "Number2","age" : 22},{"id" : "3","name" : "Number3","age" : 33}]
d2 = {"persons" :[{"id" : 1,"name" : "Number1","age" : 11},{"id" : "2","name" : "Number2","age" : 22},{"id" : 3,"name" : "Number3","age" : 33}]}
d3 = {"code" : 200, "persons" :[{"id" : 1,"name" : "Number1","age" : 11},{"id" : True,"name" : "Number2","age" : 22},{"id" : 3,"name" : "Number3","age" : 33}]}## 获取 json 数组或json 对象的 key 列表
