Simple argparse example wanted: 1 argument, 3 results

by

Here’s the way I do it with argparse (with multiple args):

parser = argparse.ArgumentParser(description='Description of your program')
parser.add_argument('-f','--foo', help='Description for foo argument', required=True)
parser.add_argument('-b','--bar', help='Description for bar argument', required=True)
args = vars(parser.parse_args())

args will be a dictionary containing the arguments:

if args['foo'] == 'Hello':
    # code here

if args['bar'] == 'World':
    # code here

In your case simply add only one argument.
