使用 Python 中的 YouTube Data API v3 将视频上传到 YouTube 并将其添加到播放列表

我编写了一个脚本，在 python 中使用 YouTube Data API v3 将视频上传到 YouTube，并借助中给出的示例示例代码 https://developers.google.com/youtube/v3/guides/uploading_a_video.

我编写了另一个脚本，使用相同的 YouTube Data API v3 将上传的视频添加到播放列表，您可以看到here https://github.com/alokmahor/add_to_youtube_playlist/blob/master/playlist.py

之后，我编写了一个脚本来上传视频并将该视频添加到播放列表。在我负责身份验证和范围的情况下，我仍然收到权限错误。这是我的新脚本

我不知道出了什么问题。我收到权限错误。两个脚本独立运行都很好。

谁能帮我找出我错在哪里或者如何实现上传视频并添加播放列表。

我得到的答案实际上在两个独立的脚本范围是不同的。
上传范围是“https://www.googleapis.com/auth/youtube.upload https://www.googleapis.com/auth/youtube.upload"
添加到播放列表的范围是“https://www.googleapis.com/auth/youtube https://www.googleapis.com/auth/youtube"

由于范围不同，所以我必须单独处理身份验证。
