Argumentparser () # Add parameter and Description parser.add_argument ("echo", help = "echo the string") args = Parser.parse_args () pri NT Args.echo" "ImportArgparseparser=Argparse. Argumentparser ()#Remember the description typeParser.add_argument ("Square", help="display a square of a given number", type=int) args=Parser.parse_args ()PrintArgs.square**2
