def second_index(a_list, number): Accepts a list of integers and an integer, and returns the index of the SECOND occurrence of the integer in the list. It returns None if the number does not occur two or more times in the list. Example 1: second_index ([2,34,3,45,34,45,3,3), 3) returns 6 Example 2: second_index( [2,34,3,45,34,45,3,3), 45) returns 5 Example 3: second_index ( [2,34,3,45,134,45,3,3), 134) returns None Example 4: second_index( [2,34,3,45, 134,45,3,3), 100) returns None return None def hasEveryLetter(s): s is a string Returns True if every letter of the (lowercase) alphabet can be found (at least once) in s, False otherwise return None
