如何將字典中的嵌套值更改為上級鍵

如何將字典中的嵌套值更改為上級鍵

拉風的咖菲貓 2021-03-29 13:54:36
我有特定格式的json文件，但我想將其更改為需要拾取其中一個嵌套值并將其投影為上級鍵的格式我只嘗試了stackoverflow的建議，并很累地達到了特定的嵌套值，但是我無法提高它。data = open('sampleDemo.json','r')json_decode=json.load(data)for item in data:    mydict={}    mydict['spk1'] = item.get('audioResponse').get('startTime').get('emotion').get.....    print mydict所需的輸出：輸入文件如下所示：{   "audioResponse": [  {     "speaker":"spk1",     "startTime": "0.0",     "endTime": "15.239",     "emotion": "neutral",     "emotionScore": "0"  },  {     "speaker":"silence",     "startTime": "15.240",     "endTime": "16.900",     "emotion": "NA",     "emotionScore": "NA"  },  {     "speaker":"spk2",     "startTime": "16.932",     "endTime": "27.320",     "emotion": "happy",     "emotionScore": "2"  },  {     "speaker":"spk1",     "startTime": "27.977",     "endTime": "37.900",     "emotion": "anger",     "emotionScore": "-3"  } ]}

您可以將組形成的屬性設置為動態(tài)


'use strict';


let attribute = 'speaker'; // can be 'speaker' or 'emotion' or 'emotionScore'

let output = {

  audioResponse: []

};


for (let response of data.audioResponse) {

  let groupKey = response[attribute];

  let group = output.audioResponse[groupKey];

  delete response[attribute]; //remove the key

  if (group) {

    group.push(response);

  } else {

    group = [response];

  }

  output.audioResponse[groupKey] = group;

}


console.log(output);
