Hi Sunil,
Try a simpler but related problem first. Say that you have two lists of numbers, like: ###### nums1 = [3, 1, 4] nums2 = [2, 7, 1] ###### Can you design a function addLists() that takes two lists of numbers of equal length, and adds them together? For example, addLists(nums1, nums2) == [5, 8, 5] should be true, as well as: addLists([4, 6], [8, 5]) == [12, 11] Would you be able to write the addLists() function? Would you be able to write a few test cases to check that the implementation works on those examples? _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
