input: Write a function to calculate the cube of a given integer and print the result. 
  def cube_calculator():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
  assert cube_calculator(-2)=="The cube of the number is: -8"
  assert cube_calculator(3)=="The cube of the number is: 27"
  assert cube_calculator(0)=="The cube of the number is: 0"
  assert cube_calculator(1)=="The cube of the number is: 1"
  assert cube_calculator(-1)=="The cube of the number is: -1"
output: def cube_calculator(number):
