Unpacking arguments from argparse

I've been writing some command line python programs and using argparse to do it. I've been structuring my code somewhat as follows.

def main(arg1, arg2):
    # magic
    pass

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('arg1')
    parser.add_argument('arg2')

    args = parser.parse_args()

    main(args.arg1, args.arg2)

It's really super irritating to have to call out arg1 and arg2 3 times. I understand having to do it twice.

Is there some way to treat the namespace returned by the parse_args function as a tuple? Or better yet as a tuple and a dict for optional args and do unpacking?

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('arg1')
    parser.add_argument('arg2')
    parser.add_argument('--opt-arg', default='default_value')

    args, kwargs = parser.magic_method_call_that_would_make_my_life_amazing()

    # I get goosebumps just thinking about this
    main(*args, **kwargs)
