如何将熊猫数据框从praw保存到xlsx？

Question

我正在尝试将数据框保存到Colab中的xlsx。我通过praw获取数据：

sm = reddit.submission(url="https://www.reddit.com/r/AskReddit/comments/1irtkq/taxi_drivers_whats_the_deepest_secret_youve/")
sm.comments.replace_more(limit=0)

data = []

for top_level_comment in sm.comments.list():
  data.append([top_level_comment.body,
               top_level_comment.author,
               top_level_comment.score,
               top_level_comment.created_utc,
               top_level_comment.depth,
               top_level_comment.id,
               top_level_comment.parent_id])

df = pd.DataFrame(data, columns=['body', 'author', 'score', 'created_utc', 'depth', 'id', 'parent_id'])
df

一切看起来都很好，我得到了所有数据。但是，当我保存它时，在Praw库中出现错误：

directory = '/content/downloads'
file_path = posixpath.join(directory, 'reddit.xlsx')
if not os.path.exists(directory):
  os.makedirs(directory)

with pd.ExcelWriter(file_path, engine='xlsxwriter') as writer:  
  df.to_excel(writer, sheet_name='Sheet1', index=False)
  worksheet = writer.sheets['Sheet1']
  writer.save()

NotFound: received 404 HTTP response

我很困惑：我已经有了数据。我不再需要http requests。

我发现最后一个熊猫错误大约是timezones。发生了什么事？

raise ValueError(
                "Excel does not support datetimes with "
                "timezones. Please ensure that datetimes "
                "are timezone unaware before writing to Excel."
            )
