This module for mutable linear homogeneous arrays is already included in 
Python since long ago.  It does not compete with the next two.

Numpy is the original multidimensional array numerical computation package 
from about a decade ago.  As far as I know, it is no longer being 
supported/upgraded.  However, it is still used be other packages that 
people use.

Numarray is a newer package that I believe is intended to replace numpy and 
which has only recently reached perhaps the same level of stability.
