And this gives you what you want? With e.g. 13=1, 14=2, 22=10, 23=11, 24=0, 25 = 1, etc. Seems unusual that that's what you would want. Also note this gives an 0 to 11 range for the results, not 0 to 12. Anyway, x %= 12 will give the same results. -- https://mail.python.org/mailman/listinfo/python-list
