python日志管理

开发过程中日志管理是很重要的，Java中有 log4j插件，具体格式为时间、类型、日志内容，那么python中如何构建这个日志

# -*- coding: utf-8 -*-import datetimeimport loggingimport logging.handlersimport os# import fileutildef log(log_message, log_file = 'log.txt', terminator_print = False):#    if terminator_print:#        try:#            print log_message#        except:#            print 'An exception occured when print log message.'    bug_file = file(log_file, 'a')    date_time = datetime.datetime.now()    bug_file.write(date_time.strftime('%Y-%m-%d %H:%M:%S') + '\n')    bug_file.write(log_message + '\n')    bug_file.close()def write(message, aim_file):    aim_file = file(aim_file, 'a')    aim_file.write(message)    aim_file.close()class logger(object):    def __init__(self, name = 'root', log_level = logging.DEBUG, log_filename = os.path.join('log', 'log.txt'), maxBytes = 1000000, backupCount = 5):        self.logger = logging.getLogger(name)        self.logger.setLevel(log_level)        log_directory = os.sep.join(log_filename.split(os.sep)[:-1])        if (not os.path.exists(log_directory)) or (not os.path.isdir(log_directory)):            os.makedirs(log_directory)        handler = logging.handlers.RotatingFileHandler(log_filename, maxBytes = maxBytes, backupCount = backupCount)        formatter = logging.Formatter('%(asctime)s %(levelname)s %(filename)s %(lineno)d %(module)s %(funcName)s %(message)s')        handler.setFormatter(formatter)        self.logger.addHandler(handler)    def settings(self, name = 'root', log_level = logging.DEBUG, log_filename = os.path.join('log', 'log.txt'), maxBytes = 1000000, backupCount = 5):        self.__init__(name, log_level, log_filename, maxBytes, backupCount)logger = logger()if __name__ == '__main__':    logger.logger.critical('This is a critical.')    logger.logger.debug('This is a debug.')    logger.logger.info('This is a info.')    logger.logger.error('This is an error.')    logger.logger.exception('This is an exception.')
