These are the scripts I use to create the playlists for the AI Class (available here: http://www.mrspeaker.net/2011/10/26/ai-class-playlists/). It's not pretty, but it works. I put them up here due to popular demand.

The first stage is to grab the video list HTML from YouTube and extract/sort the videos. This is done with the Video_ID_scraper.html file (instructions there).

Next, paste the video info into the YouTube_Playlist_Uploader.py script and it generates the playlist. It relies on the GData APIs so you need a dev key etc.

Any questions to mrspeaker@gmail.com

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!
