app = (

    .version("0.1.0")  # Version of the app.
    .arg_required_else_help(True)  # If no args passed show help message.
    .arg(Arg("--name", "-n").help("Name of the person to greet").required(True))
    .arg(
        Arg("--count", "-c")
        .help("Number of times to greet")
        .default(1)
        .value_parser(int)  # tell the parser to cast arg to int.
    )
)

if __name__ == "__main__":
    args = app.parse_args()
    for _ in range(args["count"]):
        print(f"Hello {args['name']}!")
