I have updated the "Using Python for Interactive Data Analysis" tutorial to use numpy instead of numarray (finally!). There are further improvements I would like to make in its organization and formatting (in the process including suggestions others have made to that end), but I'd rather get this version out, which I believe addresses all the content changes needed to make it useful for numpy, without delaying it any further.
The tutorial, as well as other supporting material and information, can be obtained from:
http://www.scipy.org/wikis/topical_software/Tutorial
I'm sure errors remain; please let me know of any you find.
