python打log

import globimport loggingimport logging.handlersLOG_FILENAME='logging_rotatingfile_example.out'# Set up a specific logger with our desired output levelmy_logger = logging.getLogger('MyLogger')my_logger.setLevel(logging.DEBUG)# Add the log message handler to the loggerhandler = logging.handlers.RotatingFileHandler(LOG_FILENAME,                                                maxBytes=20,                                                backupCount=5,                                            )my_logger.addHandler(handler)# Log some messagesfor i in range(20):    my_logger.debug('i = %d' % i)# See what files are created    logfiles = glob.glob('%s*' % LOG_FILENAME)    for filename in logfiles:        print filename

循环打日志 ，第一个文件达到maxBytes大小后，就写入第二个文件 。。。。
