python - conflicting option string: -h argparse

Question

I'm trying to make a generic function, that python file should accept any parameter I give to it.

I can call the python file from the console like this:

1. python life_cycle_compliance.py -FNAME Ali -LNAME Mohammed (code example is with: FNAME & LNAME)
2. python life_cycle_compliance.py -Name John -Email [email protected]

It is working fine but when I wan to use:

python life_cycle_compliance.py -h

I'm getting the following error: conflicting option string: -h argparse

def params_argparse(description):
    """

    :param description:
    :return:
    """
    parser = argparse.ArgumentParser(description=description)
    # parser.add_argument("-a", dest='a', default="", required=True)
    args_list = list(reversed(sys.argv[1:]))
    print(args_list)
    while len(args_list):
        param = args_list.pop()
        parser.add_argument(param, dest=param.replace("-", ""))
        args_list.pop()
    params = parser.parse_args()
    return params


if __name__ == "__main__":
    args = params_argparse(description="this is a description")
    # create_sysarg(description="this is one")
    print(args.FNAME)
    print(args.LNAME)
