I suppose 'elegance' is in the eye of the beholder. I agree with the
previous posts, a readable for loop is probably the best way to go.
I've instead chosen to use the functional paradigm. I thought someone
might appreciate this:

p = sys.stdout.write
map(p,[str(i)+("\n"+" "*(n-1))[i%n] for i in range(1,101)])
