第一种方法：（推荐）
import logging.handlers LOG_FILE = r‘tst.log‘ handler = logging.handlers.RotatingFileHandler(LOG_FILE, maxBytes=1024 * 1024, backupCount=5, encoding=‘utf-8‘) # 实例化handler fmt = ‘%(asctime)s - %(levelname)s - %(message)s‘ formatter = logging.Formatter(fmt) # 实例化formatter handler.setFormatter(formatter) # 为handler添加formatter logger = logging.getLogger(‘tst‘) # 获取名为tst的logger logger.addHandler(handler) # 为logger添加handler logger.setLevel(logging.DEBUG) logger.info(u‘输出中文试一试‘) logger.debug(‘first debug message‘)
第二种方法：
LOG_FORMAT = "%(asctime)s - %(levelname)s - %(message)s"
DATE_FORMAT = "%m/%d/%Y %H:%M:%S %p"
logging.basicConfig(filename=‘my.log‘, level=logging.DEBUG, format=LOG_FORMAT, datefmt=DATE_FORMAT)
logging.debug("This is a debug log.")
logging.info("This is a info log.")
logging.warning("This is a warning log.")
logging.error("This is a error log.")
logging.critical("This is a critical log.")
