I need the oldest people be first on the list, here is the example of the format i have to sort:

List =[ (‘John’, ‘12345’, ‘1972-02-08’),
(‘Sara’, ‘12345’, ‘1977-07-01’),
(‘Mario’, ‘12345’, ‘1971-06-13’) ,
(‘Lucas’, ‘12345’, ‘1967-04-27’),
(‘Kiara’, ‘12345’, ‘1973-02-15’)]

Im new on python so i have some doubts on this. ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎
