Implement the function couple, which takes in two lists and returns a list that contains lists with i-th elements of two sequences coupled together. You can assume the lengths of two sequences are the same. def couple(s1, s2): "Return a list that contains lists with i-th elements of two sequences coupled together. >>> s1 = [1, 2, 3] >>> s2 = [4, 5, 6] >>> couple(s1, s2) [[1, 4], [2, 5], [3, 6]] » s3 = ['c', 6] >>> s4 = ['s', '1'] >>> couple(s3, s4) [['c', 's'], [6, '1']] assert len(sl) == len(S2) "*** YOUR CODE HERE ***" Use Ok to test your code: python3 ok - couple
