I agree, was just trying to take home the point that if at all a format string must be used (for whatever obscure reason), then it is not necesssary to know beforehand the number of values in the dictionary (or the length of list of its values) in order to to build the format string. Hope that was parseably short, though not quite exactly pithy. :-)

Why not just do: print "Specials: " + ' '.join(menu_specials.values()) -Luke _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
