  "https://www.youtube.com/watch?v=VzuBJTtwm3o"
    ]

for i in link:
  yt = pytube.YouTube(i)
  video = youtube.streams.first()

from pytube import Playlist
pl = Playlist("https://www.youtube.com/watch?v=-otyb0ngsa4&list=PL0lo9MOBetEFCNnxB1uZcDGcrPO1Jbpz8")
for video in pl.videos:

Download the youtube video's audio in Python

It will the audio file in mp4 format. Don't worry this mp4 file also support for audio. If it doesn't work then, uninstall the pytube library and reinstall. It works for me and my friends.

import pytube

url = 'https://www.youtube.com/watch?v=VzuBJTtwm3o'

youtube = pytube.YouTube(url)
video = youtube.streams.filter(only_audio=True).all()
video[0].download('./path')

You should use the ``get_highest_resolution()` after streams to get the highest resolution of the YouTube video.
