I'm not dead sure about that, but I heard recently that python's been optimized for that behaviour. That means: using += is almost as fast as joining list. Besides, "+=" is more obvious than the other choice and since performance is not a problem until it's a problem, I'd rather use it. Anyway: I wouldn't pick it for an interview question. regards Konrad -- http://mail.python.org/mailman/listinfo/python-list
