Answer 1

Being aware, you asked for argparse solution, I would like to present alternative solution using package docopt

Install it first:

$ pip install docopt

Write the code:

"""Usage:
    main.py -a ...
"""

if __name__ == "__main__":
    from docopt import docopt
    resargs = docopt(__doc__)
    print resargs

Run it to show usage instrucitons:

$ python main.py
Usage:
    main.py -a ...

Call it with your parameters:

$ python main.py -a AA BB CC
{'-a': True,
 '': ['AA', 'BB', 'CC']}

Btw. if you do not need the -a option, you shall directly allow passing the arguments. It makes usage simpler to the user.
