Hello!
I am Charli, and I used to use Khan solely on youtube, which is where the Python course is, in the computer programming playlist. There are also Python related articles on the Khan website:

Articles: http://www.khanacademy.org/search?page_search_query=python&kind=Article

I hope that's what you needed!

Thanks Charli!
