在python中获取嵌套json字符串的键

Question

{
"id": "0001",
"type": "donut",
"name": "Cake",
"ppu": 0.55,
"batters":
    {
        "batter":
            [
                { "id": "1001", "type": "Regular" },
                { "id": "1002", "type": "Chocolate" },
                { "id": "1003", "type": "Blueberry" },
                { "id": "1004", "type": "Devil's Food" }
            ]
    },
"topping":
    [
        { "id": "5001", "type": "None" },
        { "id": "5002", "type": "Glazed" },
        { "id": "5005", "type": "Sugar" },
        { "id": "5007", "type": "Powdered Sugar" },
        { "id": "5006", "type": "Chocolate with Sprinkles" },
        { "id": "5003", "type": "Chocolate" },
        { "id": "5004", "type": "Maple" }
    ]

}

在 json 字符串上方考虑，我想从这个 json 字符串中获取具有适当层次结构的所有键，例如

id，类型，名称，ppu，击球手，

然后在面糊中：面糊，浇头

连击：id，类型

在打顶：id，类型

我正在使用python，有什么办法可以达到目的吗？

如果这是一个字符串，请尝试：

import json
json.loads(your_variable)

如果这是一个 dict 将其解析为字符串并使用上面的方法。
