Chuck, based on the relation of J to NumPy as expressed by Paul and the context of Peter's opening message of this thread, to which I originally replied, imho, my reply was on topic ... of course, biased am I. MORE INFORMATION ---------------- While this -sig is primarily about Python, it appears also to be about education. I have been learning about programming since 1967 and truly think the more programming languages to which one is exposed, the better programmer she/he will become. q.v.: "Ken's life was based on the importance of education and teaching" http://www.vector.org.uk/?area=kei&page=iverson regards, gerry "If your only tool is a hammer, all of your problems tend to look like nails". (author unknown) From: "Peter Chase" <pchase@sulross.edu> Sent: Friday, February 24, 2006 3:29 PM I'm teaching some prospective K-12 teachers this summer and propose to introduce them to Python. Reasons are numerous - It's the least weird language I know. - It offers so many programming styles. - And not least, it's free SO: Any recommendations as to course textbooks? Or just go with Zelle and/or O'Reilly's latest wood rat book? - The students presumably have had programming courses already. - I would think that K-12 students would be happier if they could generate some graphics. - This is a 6-weeks course. Little leisure time. Appreciate any advice. Peter Chase Sul Ross State University
