JSON中的单引号和双引号

问题描述

我的代码:

import simplejson as json

s = "{'username':'dfdsfdsf'}" #1
#s = '{"username":"dfdsfdsf"}' #2
j = json.loads(s)

#1定义错误

#2定义是对的

听说在 Python 中 single 和 double 引号可以互换.谁能给我解释一下?

I heard that in Python that single and double quote can be interchangable. Can anyone explain this to me?

解决方案

JSON 语法 不是 Python 语法.JSON 的字符串需要双引号.

JSON syntax is not Python syntax. JSON requires double quotes for its strings.
