How to download youtube video using python

To download a YouTube video with Python, you will need to use a library called pytube. Here is an example of how you can use this library to download a YouTube video:

 
from pytube import YouTube

# Create a YouTube object with the video URL
video = YouTube('https://www.youtube.com/watch?v=VIDEO_ID')

# Get the video with the highest resolution and download it
video.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download()
 

This code will create a YouTube object using the URL of the video you want to download, then it will filter the streams to only include progressive MP4 files, which are the type of video files that can be played on most devices. It will then sort the streams by resolution and download the one with the highest resolution. Keep in mind that downloading videos from YouTube is generally against their terms of service and could be considered copyright infringement. You should always get permission from the copyright owner before downloading any videos.
