Answer:

  1. def process(lst1, lst2):
  2.    newList = []
  3.    for i in range(0, len(lst1)):
  4.        sum = lst1[i] + lst2[i]
  5.        newList.append(sum)
  6.    return newList
  8. list1 = [1, 3, 5, 7, 9]
  9. list2 = [2, 4, 6, 8, 10]
  10. print(process(list1, list2))

Explanation:

Firstly, create a function process that takes two input lists (Line 1). In the function, create a new list (Line 2). Use a for loop to traverse through the elements of the two lists and total up the corresponding elements and add the sum to the new list (Line 3 - 5). At last, return the new list (Line 6).

In the main program, create two sample list and use them as arguments to test the function process (Line 8 - 9). We shall get the output  [3, 7, 11, 15, 19].
