If you're going on a Christmas holiday somewhere with a bad or expensive internet connection, use this script to download Youtube playlists before you go.
I cobbled this together on a whim. Less than 30 lines of code, it has a CLI interface using Click (awesome Python package, by the way) and uses pytube for the downloading.
git clone https://github.com/jbeyers/downplay.git
cd downplay
virtualenv ve --python=python3.6
. ve/bin/activate
pip install -r requirements.txt
python downplay.py
If you installed it using the above instructions, activate the virtualenv:
. ve/bin/activate
Then run:
python downplay.py
The program will ask for the url of the playlist, and for the name of a target folder to download it to. The target folder name should be just a word, no slashes etc.
It will create a 'downloads' folder in the current folder, and add another folder inside it, named after the target name you gave.
You can also use the --playlist option to specify the playlist url, and the --target option to specify the name of the target folder on the commandline.
Type python downplay.py --help for a listing of the options.
