求求大佬救救孩子吧。按照书上敲的python爬取百度网盘权利的游戏案例，结果报错，其他都不报错，生成的txt文件也没有内容

这是报的错误

这是结构，就二个py文件是自己敲的，其他都是生成的

代码

mylog.py

# -*- coding: UTF-8 -*






import logging
import getpass
import sys


###定义MyLog类
class MyLog(object):
###类MyLog的构造函数
    def __init__(self):
        self.user=getpass.getuser()
        self.logger=logging.getLogger(self.user)
        self.logger.setLevel(logging.DEBUG)
        
###日志文件名
        self.logFile=sys.argv[0][0:-3]+'.log'
        self.formatter=logging.Formatter('%(asctime)-12s %(levelname)-8s %(name)-10s %(message)-12srn')
    
###日志显示到屏幕上并输出到日志文件内
        self.logHand=logging.FileHandler(self.logFile, encoding='utf8')
        self.logHand.setFormatter(self.formatter)
        self.logHand.setLevel(logging.DEBUG)
    
        self.logHandSt=logging.StreamHandler()
        self.logHandSt.setFormatter(self.formatter)
        self.logHandSt.setLevel(logging.DEBUG)
    
        self.logger.addHandler(self.logHand)
        self.logger.addHandler(self.logHandSt)
    
###日志的五个级别对应以下的五个函数
    def debug(self,msg):
        self.logger.debug(msg)
        
    def info(self,msg):
        self.logger.info(msg)
        
    def warn(self,msg):
        self.logger.warn(msg)
        
    def error(self,msg):
        self.logger.error(msg)
        
    def critical(self,msg):
        self.logger.critical(msg)
        
if __name__=='__main__':
    mylog=MyLog()
    mylog.debug(u"I'm debug 测试中文")
    mylog.info("I'm info")
    mylog.warn("I'm warn")
    mylog.error(u"I'm error 测试中文")
    mylog.critical("I'm critical")

完全一模一样，照着书敲得，对着检车一天了，一个字也没错。求求救救孩子，错误的中文翻译为：NoneType' 'NoneType' 对象不可迭代，百度看了好多类似的都和我的不一样。

救命救命，老公！
