import logging logging.basicConfig(filename='log.log', format='%(asctime)s - %(name)s - %(levelname)s -%(module)s: %(message)s', datefmt='%Y-%m-%d %H:%M:%S %p', level=10) logging.debug('debug')logging.info('info')logging.warning('warning')logging.error('error')logging.critical('critical')logging.log(10,'log') |
对于上述记录日志的功能，只能将日志记录在单文件中，如果想要设置多个日志文件，logging.basicConfig将无法完成，需要自定义文件和日志操作对象。
