for this particular example, the most pythonic way is to do nothing at all, or, if you must call it dotproduct,
from Numeric import dot as dotproduct
Downloading, installing, and getting to know numerical modules for Python is mext on my list :). However, I was under the impression that Numarray is preferred to Numeric -- is that correct? Are these two competing packages? (Hopefully this is not flame war bait...)
Numarray is the replacement for Numeric. Some people are still using Numeric for a variety of reasons, e.g. they use a package that has not been updated to use numarray, they can't afford the performance penalty that numarray has for small arrays, etc.
