【python】logging的用法

一般我的配置如下：

import logging

logger = logging.getLogger(__name__)

if os.path.exists('./log'):
    pass
else:
    os.makedirs('./log')
handler = logging.FileHandler("./log/" + datetime.datetime.now().strftime('%Y-%m-%d_%H-%M-%S') + ".log",
                              encoding='utf-8')
handler.setLevel(logging.INFO)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)
