python模块list 转json字符串_python 列表 字典转json

一、Dictionary 转为JSON

将dict转为JSON，这里利用包json

import json

aItem = {}

aItem["id"] = "2203"

aItem["title"] = "title"

aItem["subTitle"] = "sub title"

bItem = {}

bItem["id"] = "2842"

bItem["title"] = "b标题"

bItem["subTitle"] = "b副标题"

bItem["content"] = "内容"

bItem["list"] = ["a", "a 2", "b", "bb"]

aJson = json.dumps(aItem)

bJson = json.dumps(bItem, ensure_ascii=False)

print(aItem)

print(aJson)

print(bJson)

涉及到中文字符的时候，需要指定ensure_ascii=False

输出：

{'id': '2203', 'title': 'title', 'subTitle': 'sub title'}

{"id": "2203", "title": "title", "subTitle": "sub title"}

{"id": "2842", "title": "b标题", "subTitle": "b副标题", "content": "内容", "list": ["a", "a 2", "b", "bb"]}

二、list 转为JSON

接上面的代码

jsonList = []

jsonList.append(aItem)

jsonList.append(bItem)

jsonArr = json.dumps(jsonList, ensure_ascii=False)

print(jsonArr)

输出：

[{"id": "2203", "title": "title", "subTitle": "sub title"}, {"id": "2842", "title": "b标题", "subTitle": "b副标题", "content": "内容"}]

这一个JSON字符串可以在Android Studio中利用插件GsonFormat转换得到相应对象。
