Question

我正在尝试阅读以下Json文件，然后将其粘贴到csv文件中。该文件直接来自Google Cloud bigquery（出于某些原因，csv导出不起作用）。运行此代码时，我收到上述错误：

import json

#prompt the user for a file to import
filename = "C:/Users/abc/Documents/Python Scripts/news_results.json"

#Read JSON data into the datastore variable
with open(filename) as f:
    datastore = json.load(f)

Json文件的结构由文章文本，类别和置信度组成，其中文章文本包含全文新闻文章。：

[
  {
    "article_text": "Intel unveils 's photonics technology lab. Writing in the journal Nature,
Dr Paniccia - uter chips,\" he said.\n",
    "category": "/Computers & Electronics/Computer Hardware/Computer Components",
    "confidence": "0.5"
  },
  {
    "article_text": "Rank 'set to by gaming fans.\n",
    "category": "/Computers & Electronics/Consumer Electronics/Game Systems & Consoles",
    "confidence": "0.8399999737739563"
  }
]

编辑：使用Anaconda Spyder，我得到以下回溯：
