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.
