input: Write a function to create a list of cubic values from a list of numbers from 1 to 8 and print each cubic value. The function should take a list of integers as input and return nothing (since it will only print the cubic values).
  
  def print_cubic_values(numbers):
      for num in numbers:
          print(num**3)
  
  assert print_cubic_values([1, 2, 3, 4, 5, 6, 7, 8]) is None
  assert print_cubic_values([2, 3, 4, 5, 6, 7, 8, 9]) is None
output: def print_cubic_values(numbers):
      for num in numbers:
          print(num**3)
