    parser.add_argument('files', metavar='FILE', nargs='*', help='files to read, if empty, stdin is used')
    args = parser.parse_args()

    # If you would call fileinput.input() without files it would try to process all arguments.

def tree(): return defaultdict(tree)

就是这样！

console.log(window); // log the "window" object to the console
