This is my code. I am trying to make simple youtube downloader for project but it keep throwing HTTP Error: 404, although even my url is correct
You just need to update pytube to latest version 10.8.5
Just run pip install --upgrade pytube
Pytube error: urllib.error.HTTPError: HTTP Error 404: Not Found
