This is what I get: >>>> a = [4,3,2,6,7,9] >>>> b = [8,6,3,3,2,7] >>>> all(all(i>j for j in b) for i in a) >>>> all(all(i>j for j in b) for i in a) > False > How do I make it loop through the whole list? >
It has already looped. You said you wanted to "determine if the elements in a are larger or smaller than the elements in b", ok there's your answer. Check the manual and find out what does "all()" do and also check the manual about "for j in b" and you'll see that it is already looping through both lists. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
