In pure Python (w/o extension packages) there are no 2-D arrays; so either you're using lists of lists (and I wonder how you fit even one of them in memory, if they're 1215 by 1215, much less 600!) or you're already using some extension (Numeric, numarray, numpy) and aren't telling us which one. If you're using pure Python add your extension of choice, if you're using an extension already tell us which one, and in each case there will be ways to perform your manipulation tasks faster than Python-level for loops would afford.
