python-youtube-download.py

# Import the necessary libraries
from pytube import YouTube
import ffmpeg
import urllib

# Set the URL of the YouTube video you want to download
url = 'https://www.youtube.com/watch?v=VIDEO_ID'

# Use the pytube library to access the YouTube video and retrieve its streaming data
yt = YouTube(url)
stream = yt.streams.first()

# Use the ffmpeg library to convert the streaming data into a video file
video_file = ffmpeg.input(stream.url)
video_file = ffmpeg.output(video_file, 'output.mp4')

# Use Python's built-in urllib library to download the video file
urllib.request.urlretrieve(stream.url, 'output.mp4')

# Save the video file to your desired location
with open('output.mp4', 'wb') as f:
    f.write(video_file)
