A simple script to download all videos in a youtube playlist (720p quality)
#####This script needs Python 3.4.1+
$ pip3 install pytube$ python ytPlaylistDL.py <playlistURL>$ python ytPlaylistDL.py <playlistURL> <destinationPath>Say I'd like to download all videos in the playlist "FOMH 2015" (a music channel I like on youtube), found at URL https://www.youtube.com/playlist?list=PLVJcUspOFG-Np-YotXlPviRUK_MKyvwId, and put them in a music folder named ~/Music/FOMH. This is how I would do that:
$ python ytPlaylistDL.py https://www.youtube.com/playlist?list=PLVJcUspOFG-Np-YotXlPviRUK_MKyvwId ~/Music/FOMH
