Yes, I know, but I don't want to depend on
Numeric Python in this instance.  The point
in this context is transparency:  students
need to see everything.

Here's another function I like OK:

   def zeromatrix(n,m):
        output = []
        for i in range(n): output.append([0]*m)
        return output
