import glob 
import logging 
import logging.handlers 
LOG_FILENAME='logging_rotatingfile_example.out' 
# Set up a specific logger with our desired output level 
my_logger = logging.getLogger('MyLogger') 
my_logger.setLevel(logging.DEBUG) 
# Add the log message handler to the logger 
handler = logging.handlers.RotatingFileHandler(LOG_FILENAME, 
                                                maxBytes=20, 
                                                backupCount=5, 
                                            ) 
my_logger.addHandler(handler) 
# Log some messages 
for 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  。。。。
