I am glad to see the Numeric, NumArray, Numpy line mentioned in the 
context of Python and education.  It is, was and has been essential for 
me in the learning experience I have undertaken with Python. No question 
that I would have passed Python by early in the game if it was not 
there.  (JIm Huginin, late of IronPython (i.e. .Net Python started the 
processs, if I understand correctly)

And I am routing for its eventual inclusion in the standard Python 
distribution.
