The acronym for Numerical Python, advertised as "the fundamental package for scientific computing with Python." Also: "Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data."
How did I come across this? While surfing around as I submit blog posts to the Boston Globe's Brainiac blog.
NumPy: a little NIMBY, a little num (the synonym for yum), and perhaps summoning the yampi (or yampee, or cush-cush). If it were an animal, would likely be a panda.
