使用Windows 8.1执行Python 3.5.1代码时出错

Question

当我尝试运行Python程序时，我有一个关于错误的问题。我在Windows 8.1下使用Python 3.5.1。代码和错误消息附在下面。使用Python 3.5.1，代码在Mac上运行得很好。

import logging
logging.basicConfig(filename='example.log', level=logging.INFO)

def logger(func):
    def log_func(*args):
        logging.info('Running "{}" with arguments {}'.format(func.__name__, arg))
        print(func(*args))
    return log_func

def add(x, y):
    return x+y

def sub(x,y):
    return x-y

add_logger = logger(add)
sub_logger = logger(sub)

Tracback：
