looking for a neat solution to a nested loop problem

[Ian Foote]

The function range can be called with more than one argument. For example:

for i in range(N, N + 10):
     for j in range(M, M + 100):
         do_something(i, j)

You can also call range with 3 arguments, if want a step size different 
to 1:

for k in range(2, 11, 3):
     print(k)

2
5
8

Hope this is clear,
Ian
