This guide covers the most basic usage of the library. For more detailed information, please refer to pytube.io.
Pytube requires an installation of Python 3.6 or greater, as well as pip. (Pip is typically bundled with Python installations.)
To install from PyPI with pip:
$ python -m pip install pytube
Sometimes, the PyPI release becomes slightly outdated. To install from the source with pip:
$ python -m pip install git+https://github.com/pytube/pytube
Using pytube in a Python script
To download a video using the library in a script, you'll need to import the YouTube class from the library and pass an argument of the video URL. From there, you can access the streams and download them.
>>> from pytube import YouTube >>> YouTube('https://youtu.be/2lAe1cqCOXo').streams.first().download() >>> yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo') >>> yt.streams ... .filter(progressive=True, file_extension='mp4') ... .order_by('resolution') ... .desc() ... .first() ... .download()
Using the command-line interface
Using the CLI is remarkably straightforward as well. To download a video at the highest progressive quality, you can use the following command:
$ pytube https://youtube.com/watch?v=2lAe1cqCOXo
You can also do the same for a playlist:
$ pytube https://www.youtube.com/playlist?list=PLS1QulWo1RIaJECMeUT4LFwJ-ghgoSH6n
