想使用 tweepy 获取 twitter 数据但遇到了麻烦
Want to get twitter data using tweepy but in trouble
我正在尝试使用 Tweepy 检索 Twitter 数据,使用下面的代码,但我在收集 media_fields 数据时遇到了困难。特别是,我想获得媒体的类型,但我失败了。
正如您在下面看到的,该值已被复制并存在于本应为空的单元格中。

# Change this list of dictionaries into a dataframe
df = pd.DataFrame(result)
此外,当我将代码 ''media':tweet.attachments' 更改为 'media':tweet.attachments[0] 以获取 'media_key' 数据时,我得到以下错误信息。"TypeError: 'NoneType' object is not subscriptable"
我做错了什么?任何建议,将不胜感激。

可订阅错误来自于 tweet.attachments 是 None,从这里 NoneType 部分。要使其正常工作,您可以添加 None:
的检查
'media':tweet.attachments[0] if tweet.attachments else None
我从未使用过推特 API,但一件事是确保推特附件始终存在或者可能不存在。
