In most cases, argparse (http://argparse.python-hosting.com/) supports
negative numbers right out of the box, with no need to use '--':
>>> import argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-a', type=int)
>>> parser.add_argument('b', type=int)
>>> args = parser.parse_args('-a -42 -123'.split())
>>> args.a
-42
>>> args.b
-123
