Since Danny got it started with the examples, I'll give another canonical example of the use of the modulus operator. Imagine that we're trying to figure out what number the hour hand of a clock will be pointing at x hours from now. If it's one o'clock right now, in 5 hours, the hour hand will be pointing at the six, and in 10 hours, it will be pointing at the 11. However, where will it be pointing in 16 hours? Well, in 12 hours it will be at the one, then four more hours later it will be pointing at the five. This can be represented as: 1 + (16 % 12) = 1 + 4 = 5 In general, the hour at some point in the future will be: (start time) + (hours in the future % 12) Peace Bill Mill bill.mill at gmail.com _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
