It's not as bad as you think. The addition of two integers is a cheap task (in terms of computation power). If you have two way's to to it, every little think (jumps in the code etc. ) will have a larger impact on the execution time than on an expensive operation. But every improvement on your algorithm will easily result in a significant shorter execution time than replaceing a+=1 with a=a+1 will ever do. :-) -- http://mail.python.org/mailman/listinfo/python-list
