[Chicago] python intro for 13 yo -- suggestions?

[jake elliott]

hi folks

i have a 13 y/o staying here for a while and i'd like to help him find
a more rewarding way to use his time than obssessively replaying every
NES/SNES/gamecube game.

i found alan gauld's fairly python-centric 'learning to program'
online [http://www.freenetpages.co.uk/hp/alan.gauld/] which looks
pretty good but may be a little dry -- any other recommendations?
i'll be around to help him work through any tutorials.

thanks,
jake
