The only thing I recall is an exchange with John Brawley that I reported here. If I remember correctly, he was creating a VPython sphere in a fucntion, assigning a variable to the function call, and couldn't unerstand why he was getting an attribute error when trying to change the sphere's color. It was simply a matter of explaining to him that since he was not explicity asking the function to return anything, it was returning Nothing - which is Something. So that the Something which he was trying to color was actually exactly the Nothing Something. Not the Sphere Something. ;) Art _______________________________________________ Edu-sig mailing list Edu-sig@python.org http://mail.python.org/mailman/listinfo/edu-sig
