This question already has an answer here:
I want to download two series of playlists from this channel: https://www.youtube.com/user/mathdude2012/playlists
The channel has a "Biology" series of playlists and a "Biochemistry (by chapters)" series of playlists. Essentially, I want to make two directories "Biology" and "Biochemistry" that contain subdirectories that bear the name of the playlists in the series with the corresponding name on the channel. Additionally, I would like for the videos to be in order, so each video in a playlist has its index before the title and URL section of the file name. How can I accomplish this?
Thanks in advance.
