在Python中更新嵌套字典中的计数器

我使用的是一个初始值为0的空结果字典，在浏览源数据时，我希望在出现该字典时对其进行更新。字典如下所示：

{
  "Group1": {
    "1": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "2": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "3": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "4": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "5": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "6": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "not_specified": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    }
  },
  "Group2": {
    "1": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "2": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "3": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "4": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "5": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "6": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    },
    "not_specified": {
      "fr": {
        "answered": 0,
        "unanswered": 0
      },
      "nl": {
        "answered": 0,
        "unanswered": 0
      },
      "not_specified": {
        "answered": 0,
        "unanswered": 0
      }
    }
  }
}dic

当我尝试只更新给定计数器时，例如：

myDic['Group1']['1']['nl']['answered']=myDic['Group1']['1']['nl']['answered']+10
myDic['Group2']['1']['nl']['answered']=myDic['Group2']['1']['nl']['unanswered']+100

---

我用相同的值更新了整个字典中的所有计数器。原因是什么？

您当前的代码是有效的，但看起来您的

{“已回答”：0，“未回答”：0}

dict是对同一对象的引用，因此当您更改其中的值时，它会到处更改

检查

id（myDic['Group1']['1']['nl']）==id（myDic['Group1']['1']['fr']）

？ 如果是这样，在创建这些DICT时，您需要使用

from copy import deepcopy

此代码有味道，但概述清楚：

从复制导入deepcopy
原件=深度复制（myDic['Group1']['1']['nl']]
原件[“已答复”]+=10
myDic['Group1']['1']['nl']=原件

我无法再现“整个字典中更新的所有计数器具有相同的值”部分。可能是您通过复制引用创建了字典。我猜也是引用。当我在我的机器上运行你的代码时，我得到了你想要的结果。谢谢！事实上，最后一本字典是一本参考书！
