input: Write a function to calculate the cube of an input integer provided by the user. The function should take an input value, compute its cube, and print the result.
  
  def calculate_cube():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
  
  assert calculate_cube()=="Please enter a number: 3\nThe cube of the number is: 27"
  assert calculate_cube()=="Please enter a number: 5\nThe cube of the number is: 125"
  assert calculate_cube()=="Please enter a number: 0\nThe cube of the number is: 0"
  assert calculate_cube()=="Please enter a number: -2\nThe cube of the number is: -8"
  
  
  Note: The assert statements will not execute as expected because they involve user input, which cannot be directly tested in this manner. These assertions are provided purely for demonstration purposes.
output: def calculate_cube():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
