# logger可以看做是一个记录日志的人，对于记录的每个日志，他需要有一套规则，比如记录的格式（formatter），

# 等级（level）等等，这个规则就是handler。使用logger.addHandler(handler)添加多个规则，

# 就可以让一个logger记录多个日志。

  logger.addHandler(MyLog.errhandler)

 #handler=logging.FileHandler(log_filename)

 #把logger添加上handler

 logger.addHandler(MyLog.handler)

  logger.removeHandler(MyLog.errhandler)

 logger.removeHandler(MyLog.handler)

def getCurrentTime():

 return time.strftime(MyLog.dateformat,time.localtime(time.time()))

 MyLog.debug("This is debug message")

 MyLog.info("This is info message")

 MyLog.warning("This is warning message")
