input: Write a function to calculate the cube of a given integer input. The function should prompt the user to enter a number, calculate its cube, and print the result.
  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"
  assert calculate_cube()=="Please enter a number: 10\nThe cube of the number is: 1000"
output: def calculate_cube():
      number = int(input("Please enter a number: "))
      cube = number**3
      print("The cube of the number is: " + str(cube))
