Understood. In this case, the first half dozen variables are input and the rest are derived from the first ones. A class might make sense and though I understand them a little, not enough to make a good judgement on it. The task is to take parameters for a scuba dive; depth, gas mix, time, air consumption rate, and compute the O2 load, gas required, etc. Leam -- Mind on a Mission <http://leamhall.blogspot.com/> _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
