talk is cheap，show me the code.

            
              import logging
import logging.handlers

logger = logging.getLogger("logger")

handler1 = logging.StreamHandler()
# handler2 = logging.FileHandler(filename="test.log", encoding="utf-8")
# 每隔 1000 Byte 劃分一個日志文件，備份文件為 3 個
# handler2 = logging.handlers.RotatingFileHandler("test.log", mode="w", maxBytes=1000, backupCount=3, encoding="utf-8")

# 每隔 1分鐘 劃分一個日志文件，interval 是時間間隔，備份文件為 10 個
# handler2 = logging.handlers.TimedRotatingFileHandler("test.log", when="M", interval=1, backupCount=10)

logger.setLevel(logging.DEBUG)
handler1.setLevel(logging.DEBUG)
# handler2.setLevel(logging.WARNING)

formatter = logging.Formatter("%(asctime)s %(name)s %(levelname)s %(message)s")
handler1.setFormatter(formatter)
# handler2.setFormatter(formatter)

logger.addHandler(handler1)
# logger.addHandler(handler2)

# print(handler1.level)
# print(handler2.level)
# print(logger.level)
# logging.disable(logging.WARNING)
# logger.disabled = True

# logger.debug('哈哈This is a customer debug message')
# logger.info('This is an customer info message')
# logger.warning('嘎嘎This is a customer warning message')
# logger.error('This is an customer error message')
# logger.critical('This is a customer critical message')
