input: Write a function that takes an integer input from the user and prints the cube of that number. Function should be named 'print_cube'. Once the user inputs a number, it should compute the cube of this number and print it.
  assert print_cube()==The cube of the number is: 27 (assuming user inputs 3)
  assert print_cube()==The cube of the number is: 64 (assuming user inputs 4)
  assert print_cube()==The cube of the number is: 125 (assuming user inputs 5)
output: def print_cube():
      number = int(input())
      cube = number ** 3
      print(f"The cube of the number is: {cube}")
