使用python在JSON键周围添加双引号

Question

如果我有一个“json数据”，没有双键引号，就像这样：

{
  id: "2f5677f06f7efe6db340feffdd0ae0ae",
  messageId: "AM9wimIAAARJU6noVQkvkFLzouM",
  tp: "test",
  data: {
      itemShipped: [
       {
        additionalProperties: {},
        offers: {
             price: "$5.97",
             additionalProperties: {},
             name: "",
             seller: {
                additionalProperties: {},
                name: "SF Planet",
                url: "xxx.com"
           }
        },
      name: "Fosmon DURA",
      image: "images-amxxxazxxxon",
      url: "http://www.zzz.com"
  }
] }}

然后如何在python的所有键周围添加双引号？谢谢！
