如何使用python在JSON中添加父对象

Question

我有这个 json，它有 3 个父元素和每个父元素下的几个子元素。我想为所有 3 个当前父母添加一个共同的父母。

目前我有：

 {
  "Parent1": {
    "Key1": "Value",
    "Key2": "Value",
    "Key3": "Value"
},
  "Parent2": {
    "Key1": "Value",
    "Key2": "Value",
    "Key3": "Value"
  },
  "Parent3": {
    "Key1": "Value",
    "Key2": "Value",
    "Key3": "Value"
  }
}

我想要的：

{
  "Main parent": {
    "Parent1": {
      "Key1": "Value",
      "Key2": "Value",
      "Key3": "Value"
    },
    "Parent2": {
      "Key1": "Value",
      "Key2": "Value",
      "Key3": "Value"
    },
    "Parent3": {
      "Key1": "Value",
      "Key2": "Value",
      "Key3": "Value"
    }
  }
}

下面的 python3 代码不起作用：

with open ("myfile.json", 'r') as f:
    myjson = json.load(f)

myjson["Main Parent"] = myjson

如果您对这种情况有所了解，我将不胜感激。

Answer 1

with open ("myfile.json", 'r') as f:
    myjson = json.load(f)

myjson = {'Main Parent': myjson}

Answer 2

您可以创建一个新的dict并映射Main Parent到您的子 JSON：

new_json = dict()
new_json["Main Parent"] = myjson
