Quickstart
mp4 video download highest resolution:
from pytubefix import YouTube
from pytubefix.cli import on_progress

url = "url"

yt = YouTube(url, on_progress_callback = on_progress)
print(yt.title)

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):
from pytubefix import YouTube
from pytubefix.cli import on_progress

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 Playlist
from 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 YouTube
from 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

Subtitle/Caption Tracks:
viewing available subtitles:
from pytubefix import YouTube

yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')
subtitles = yt.captions

print(subtitles)

printing the subtitle tracks:
from pytubefix import YouTube

yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')

caption = yt.captions.get_by_language_code('en')
print(caption.generate_srt_captions())

now you can save subtitles to a txt file:
from pytubefix import YouTube

yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')

caption = yt.captions.get_by_language_code('en')
caption.save_captions("captions.txt")

Using Channels:
get the channel name:
from pytubefix import Channel

c = Channel("https://www.youtube.com/@ProgrammingKnowledge/featured")

print(f'Channel name: {c.channel_name}')

to download all videos from a channel:
from pytubefix import Channel

c = Channel("https://www.youtube.com/@ProgrammingKnowledge")

print(f'Downloading videos by: {c.channel_name}')

for video in c.videos:
download = video.streams.get_highest_resolution().download()

>>> from pytubefix import Search
