You might look at argparse_ which allows you to treat positional
arguments just like optional ones.  So you'd write::

    parser = argparse.ArgumentParser()
    parser.add_argument('command') # positional argument
    parser.add_argument('--option') # optional argument
    args = parser.parse_args()
    ... args.command ...
    ... args.option ...

If you're really insistent on a dict interface instead of an attribute
interface, the object returned by parse_args() is just a simple
namespace, so vars(args) will give you a dict.
