Store argparse input to use as variable

I am using argparse to require input from the user for a hardware id to then be called later on, I cannot work out how to get it so the user types

<command> --id <id>

Please help me see where I’m going wrong! Thanks

parser = argparse.ArgumentParser(description='Return a list of useful information after specifying a hardare/asset ID')
parser.add_argument('--id', type=str, required=True, help ='A hardware/asset id to provide information on')
args = vars(parser.parse_args())
args = parser.parse_args()

def main():
    hardware_id = hardware_id_input
    host = get_host_information(hardware_id)
    print(host["hostname"])
    print(host["hardware_id"])

>Solution :

Ditch the call to vars. You would have your argument stored as args.id after parsing. You would then call your main with the args.id as input.
