Python通用logging方法：控制台输出以及文件自动切分

import logging
from logging.handlers import TimedRotatingFileHandler

import sys

def get_logger():
    logger = logging.getLogger()
    hd = logging.StreamHandler(sys.stdout)
    # hd = TimedRotatingFileHandler('mylog.log', when='D',maxBytes=10240000 backupCount=30)
    formatter = logging.Formatter("%(asctime)s - %(levelname)s - %(message)s")
    hd.setFormatter(formatter)
    logger.addHandler(hd)
    logger.setLevel(logging.DEBUG)
    return logger
