yy goes from 1 to maxy-1, xx goes from 1 to maxx-1, there are  
(maxy-1)*(maxx-1) squares generated. Is that what you want?

Here, you're counting from 1 to maxy inclusive.

Why don't you use the same two-loop design both times? Or better, use a  
bidimensional data structure (like a list of lists, or the numpy library  
if you're mostly concerned with numbers).
