[SciPy-user] changing the default data type of zeros and ones

Sorry, this is a pylab/numpy incompatibility problem.  In order to not
spend a lot of time talking about namespaces and such, I teach them to
put

from scipy import *
from pylab import *

at the beginning of every script and from there it will kind of feel
like Matlab.  It is pylab.zeros and pylab.ones that is the problem.

How do I best explain this to my students?
