将 csv 数据转换为嵌套的 json 数据

Question

我有一个 csv 数据：

<块引用>

dataf = pd.DataFrame{'title':['tit1', 'tit1', 'tit2' 'tit2','tit3'], 'context':['con1', 'con1', 'con2', 'con2', 'con3'], '答案':['text1', 'text2', 'text3', 'text4', 'text5'], '问题':['que1', 'que2', 'que3', 'que4', 'que5'], 'id':['DDA', 'SAV', 'AFS', 'ML', 'MLI']}

我想使用 python 将其转换为嵌套的 json 格式，如下所示：

[
  {
    "title": "tit1",
    "paragraph": [
      {
        "context": "con1",
        "qas": [
          {
            "answers": "text1",
            "question": "que1",
            "id": "DDA"
          },
          {
            "answers": "text2",
            "question": "que2",
            "id": "SAV"
          }
        ]
      }
    ]
  },
  {
    "title": "tit2",
    "paragraph": [
      {
        "context": "con2",
        "qas": [
          {
            "answers": "text3",
            "question": "que3",
            "id": "AFS"
          },
          {
            "answers": "text4",
            "question": "que4",
            "id": "ML"
          }

        ],
        "context": "con3",
        "qas": [
          {
            "answers": "text5",
            "question": "que5",
            "id": "MLI"
          }
        ]

      }
    ]
  }
]
