Couple 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 q3: enumerate implement enumerate, which pairs the elements of a sequence with their indices, offset by a starting value. enumerate takes a sequence s and a starting value start. it returns a list of pairs, in whichthei-th element is i + start paired with the i-th element of s. for example: > > > enumerate(['maps', 21, 47], start=1) > > > [[1, 'maps'], [2, 21], [3, 47]] hint: consider using couple from question 2! hint 2: you may find the built in range function . def enumerate(s, start=0): "" "returns a list of lists, where the i-th list contains i+start and the i-th element of s. > > > enumerate([6, 1, 'a']) [[0, 6], [1, 1], [2, 'a']] > > > enumerate('five', 5) [[5, 'f'], [6, 'i'], [7, 'v'], [8, 'e']] "*** your code here ***"

The big bang nucleosynthesis theory states that elements were produced in the first few minutes of the big bang while elements have their origins in the interiors of stars, forming much later in the history of the universe.
