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.

I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
