Another question

Jeff -

The main reason (AFAIK) you don't want to do 'from <mod> import *' is to
avoid namespace clashing.
A better way is this:

#untested
import random
randint = random.randint

for i in xrange(1,1000000):
    print randint(1,10)

#

This method allows you to control exactly which names you import into
your local namespace form the module.  The above should also be a little
faster due to the use of xrange.  Se the docs for why.
