ys = yt.streams.get_highest_resolution()ys.download()

If you want to save in .mp3 just pass the mp3=True parameter (MPEG-4 AAC audio codec):

 url = "url"
 yt = YouTube(url, on_progress_callback = on_progress)print(yt.title) 
ys = yt.streams.get_audio_only()ys.download(mp3=True)

if you want to download complete playlists:

from pytubefix import Playlistfrom pytubefix.cli import on_progress
 url = "url"pl = Playlist(url)for video in pl.videos:ys = video.streams.get_audio_only()ys.download(mp3=True)

if you want to add authentication

from pytubefix import YouTubefrom pytubefix.cli import on_progress
 url = "url"yt = YouTube(url, use_oauth=True, allow_oauth_cache=True, on_progress_callback = on_progress)           
ys = yt.streams.get_highest_resolution()ys.download() # you will only get the request to authenticate once you download

if you want to download a video to a specific directory:

from pytubefix import YouTubefrom pytubefix.cli import on_progressurl = "url"yt = YouTube(url, on_progress_callback = on_progress)ys = yt.streams.get_highest_resolution()ys.download(output_path="path/to/directory")

from pytubefix import YouTube
 yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')caption = yt.captions['a.en']print(caption.generate_srt_captions())

now you can save subtitles to a txt file:
