python中json格式数据输出的简单实现方法

主要使用json模块，直接导入import json即可。

小例子如下：

#coding=UTF-8
import json

info={}
info["code"]=1
info["id"]=1900
info["name"]='张三'
info["sex"]='男'

list=[info,info,info]

data={}
data["code"]=1
data["id"]=1900
data["name"]='张三'
data["sex"]='男'
data["info"]=info
data["data"]=list

jsonStr = json.dumps(data)

print "jsonStr:",jsonStr

关键代码：jsonStr = json.dumps(data)
<span style="font-family:Arial;BACKGROUND-COLOR: #ffffff">执行输出如下：</span>
jsonStr: {"info": {"code": 1, "sex": "\u7537", "id": 1900, "name": "\u5f20\u4e09"}, "code": 1, "name": "\u5f20\u4e09", "sex": "\u7537", "data": [{"code": 1, "sex": "\u7537", "id": 1900, "name": "\u5f20\u4e09"}, {"code": 1, "sex": "\u7537", "id": 1900, "name": "\u5f20\u4e09"}, {"code": 1, "sex": "\u7537", "id": 1900, "name": "\u5f20\u4e09"}], "id": 1900}
