i would use the first method. - it makes explicit that do_first_calculation() is computing something needed by the second - you could give the variable a better name which would make it easier to understand calculate_something() - answer is not part of the state of self and it has no meaning outside of calculate_something(), so don't clutter up self with the extra value. kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
