在把日志写入文件的同时在控制台输出
示例代码如下：
#coding=utf-8import loggingimport timeimport osdir = os.path.dirname(os.path.abspath('.'))log_path = dir + '\\log'class Log:def __init__(self):self.logname = os.path.join(log_path, '{0}.log'.format(time.strftime('%Y-%m-%d')))def __printconsole(self, level, message):# 创建一个loggerlogger = logging.getLogger()logger.setLevel(logging.DEBUG)# 创建一个handler，用于写入日志文件fh = logging.FileHandler(self.logname,'a',encoding='utf-8')fh.setLevel(logging.DEBUG)# 再创建一个handler，用于输出到控制台ch = logging.StreamHandler()ch.setLevel(logging.DEBUG)# 定义handler的输出格式formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')fh.setFormatter(formatter)ch.setFormatter(formatter)# 给logger添加handlerlogger.addHandler(fh)logger.addHandler(ch)# 记录一条日志if level == 'info':logger.info(message)elif level == 'debug':logger.debug(message)elif level == 'warning':logger.warning(message)elif level == 'error':logger.error(message)logger.removeHandler(ch)logger.removeHandler(fh)# 关闭打开的文件fh.close()def debug(self,message):self.__printconsole('debug', message)def info(self,message):self.__printconsole('info', message)def warning(self,message):self.__printconsole('warning', message)def error(self,message):self.__printconsole('error', message)if __name__ == '__main__':log = Log()log.info('info msg1000013333')log.debug('debug msg')log.warning('warning msg')log.error('error msg')
输出结果如下：
> "D:\Python27\python.exe" "D:\work\code\test\test\wirteLog.py" -05-09 15:09:32,763 - root - INFO - info msg1000013333-05-09 15:09:32,769 - root - DEBUG - debug msg-05-09 15:09:32,776 - root - WARNING - warning msg-05-09 15:09:32,782 - root - ERROR - error msg
