从字典中检索所有键

  • 772

有字典，但字典里有字典。如何从“数据”中提取所有键并将它们放入单独的字典中

questionnaire = {
      "appType":"value",
      "step":"FULL",
      "data":{
        "amount":50000,
        "period":36,
        "loanPurpose":"ConstructionHouseroom",
      }
}
python

  1. Best Answer
    questionnaire = {
      "appType":"value",
      "step":"FULL",
      "data":{
        "amount":50000,
        "period":36,
        "loanPurpose":"ConstructionHouseroom",
      }
}

print(list(questionnaire["data"].keys()))

    结果：

    ['amount', 'period', 'loanPurpose']
