python - 如何将新对象添加到嵌套字典中？

Question

给定以下对象，如何在“加州”中添加一个新城市“洛杉矶”？给定国家、州、城市和城市的属性，我该如何更新对象？ (我对 python 很陌生)

myplaces = {
  "unitedstates": {
    "california": {
      "sanfrancisco": {
        "description": "Tech heaven",
        "population": 1234,
        "keyplaces": ["someplace1",
          "someplace2"]
      }
    }
  },
  "india": {
    "karnataka": {
      "bangalore": {
        "description": "IT hub of India",
        "population": 12345,
        "keyplaces": ["jpnagar",
          "brigade"]
      },
      "mysore": {
        "description": "hostoric place",
        "population": 12345,
        "keyplaces": ["mysorepalace"]
      }
    }
  }
}

我尝试添加如下元素(就像在 PHP 中的做法一样):

myplaces['unitedstates']['california']['losangeles']['description'] = 'Entertainment'

编辑: 这不是重复的。我正在寻找一种添加项目的通用方法。

你快搞定了 -

myplaces['unitedstates']['california']['losangeles'] = {'description':'Entertainment'}
