We have a number of apples, n. We need to determine how many bags of apples we can fill (each bag holds exactly a dozen apples), and we want to know how many apples would be left over after we filled the bags.

Which of the following will calculate num_of_bags and left_over variables? (python)

a) num_of _bags= n//12

left_over = n /12

b) num_of_bags = n // 12

left_over = n % 12
