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。
