  def print_cube():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
  
  assert print_cube==The cube of the number is: 8  #if input is 2
  assert print_cube==The cube of the number is: 27  #if input is 3
  assert print_cube==The cube of the number is: 1  #if input is 1
  assert print_cube==The cube of the number is: 125  #if input is 5
  assert print_cube==The cube of the number is: 64  #if input is 4
output: def print_cube():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
