numpy is the successor to numarray, so if you are just starting with arrays,
please get started with numpy. It should also be noted that numpy can create
arrays of objects as well as arrays of numbers.
In : from numpy import *
In : empty((1,2,3), dtype=object)
array([[[None, None, None],
[None, None, None]]], dtype=object)
"I have come to believe that the whole world is an enigma, a harmless enigma
that is made terrible by our own mad attempt to interpret it as though it had
an underlying truth."
-- Umberto Eco
