本文实例讲述了python根据文件大小打log日志的方法,分享给大家供大家参考。具体方法如下:
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
该实例可实现循环打日志 ,第一个文件达到maxBytes大小后,就写入第二个文件。
希望本文所述对大家的Python程序设计有所帮助。
