input: Write a function to print the cubic values of numbers in a list from 1 to 8. The function should take a list of numbers and for each number in the list, it should print its corresponding cubic value. If the list is empty, the function should print a message stating that the list is empty.
  
  assert print_cubic_values([1, 2, 3, 4, 5, 6, 7, 8]) is None
  assert print_cubic_values([]) is None
output: def print_cubic_values(numbers):
      if not numbers:
          print("The list is empty")
      else:
          for num in numbers:
              print(num ** 3)
