Python 如果要写入Json文件的数据结构不正确，该怎么办？

我试图使用API和Python检索数据，然后将其保存在Json文件中

不幸的是，API返回的数据结构非常糟糕，因此我无法以编程方式搜索该文件

然后，数据如下所示：

{
  "data": [
    [
      [],
      null
    ],
    [
      [
        {
          "1. symbol": "YI",
          "2. name": "111 Inc.",
          "3. type": "Equity",
          "4. region": "United States",
          "5. marketOpen": "09:30",
          "6. marketClose": "16:00",
          "7. timezone": "UTC-05",
          "8. currency": "USD",
          "9. matchScore": "0.3636"
        }
      ],
      null
    ],
    [
      [
        {
          "1. symbol": "2GB.DEX",
          "2. name": "2G Energy AG",
          "3. type": "Equity",
          "4. region": "XETRA",
          "5. marketOpen": "08:00",
          "6. marketClose": "20:00",
          "7. timezone": "UTC+02",
          "8. currency": "EUR",
          "9. matchScore": "0.5714"
        },
        {
          "1. symbol": "2GL.FRK",
          "2. name": "Gaming and Leisure Properties Inc.",
          "3. type": "Equity",
          "4. region": "Frankfurt",
          "5. marketOpen": "08:00",
          "6. marketClose": "20:00",
          "7. timezone": "UTC+02",
          "8. currency": "EUR",
          "9. matchScore": "0.5714"
        }
      ],
      null
    ]
  ]
}

我设法在保存之前过滤掉None，但括号保留并破坏了结构

有人知道我怎样才能使这些数据结构良好吗？我使用的是Python 3.8

嗯，这里肯定有一个模式。 基本上，数据结构如下：

{
   "data":[ 
        [[<values you look for>], null],
        [[<values you look for>], null]
    ]
}

您将得到一个简单的dict列表。

您的json结构非常好，只需使用

json

库正确处理数据即可：

import json

data = """{
  "data": [
    [
      [],
      null
    ],
    [
      [
        {
          "1. symbol": "YI",
          "2. name": "111 Inc.",
          "3. type": "Equity",
          "4. region": "United States",
          "5. marketOpen": "09:30",
          "6. marketClose": "16:00",
          "7. timezone": "UTC-05",
          "8. currency": "USD",
          "9. matchScore": "0.3636"
        }
      ],
      null
    ],
    [
      [
        {
          "1. symbol": "2GB.DEX",
          "2. name": "2G Energy AG",
          "3. type": "Equity",
          "4. region": "XETRA",
          "5. marketOpen": "08:00",
          "6. marketClose": "20:00",
          "7. timezone": "UTC+02",
          "8. currency": "EUR",
          "9. matchScore": "0.5714"
        },
        {
          "1. symbol": "2GL.FRK",
          "2. name": "Gaming and Leisure Properties Inc.",
          "3. type": "Equity",
          "4. region": "Frankfurt",
          "5. marketOpen": "08:00",
          "6. marketClose": "20:00",
          "7. timezone": "UTC+02",
          "8. currency": "EUR",
          "9. matchScore": "0.5714"
        }
      ],
      null
    ]
  ]
}"""

data_json = json.loads(data)

输出

{'data': [[[], None],
  [[{'1. symbol': 'YI',
     '2. name': '111 Inc.',
     '3. type': 'Equity',
     '4. region': 'United States',

你认为什么是“结构良好”？您尝试过将数据获取到所需的输出吗？我不知道为什么会出现空值，这是我的问题。我没有看到图案，所以谢谢你，先生：）
