我有一个运行时间很长的 python 代码，它调用多个 api。

我还在每一步都实现了记录器来识别异常。但是，FileHandler 仅在 python 脚本完成时显示数据。

有没有办法在固定间隔后刷新记录器？我可以用它来监控工作的状态。

# when executed standalone, the main block is called    
if __name__ == '__main__':

    # Crate logger for RR api application
    logger = logging.getLogger('RR_API')
    logger.setLevel(logging.INFO)

    # create file handler which logs messages
    # If the handler is already defined, then no need to set it again
    if not logger.handlers:
        fh = logging.FileHandler("C:///Users///2128///python_data_logger.log")
        fh.setLevel(logging.DEBUG)

    # create formatter and add it to the handlers
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    fh.setFormatter(formatter)

    #add the handlers to the logger
    logger.addHandler(fh)

    run_ts = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    logger.info('Starting Time' + '|' + run_ts)
    print ('Starting Time',datetime.now().strftime('%Y-%m-%d %H:%M:%S'))
    count = 0
    token = get_temp_token(run_ts)
    portfolio = get_orgs(token,'"https://apidata.ratings.com/v1.0/orgs/"',run_ts)

日志文件中的输出：

2016-12-30 16:22:01,448 - RR_API - INFO - Starting Time|2016-12-30 16:22:01
2016-12-30 16:22:01,526 - RR_API - CRITICAL - No Access Token was downloaded | 2016-12-30 16:22:01

仅当脚本执行终止时，上述行才在日志文件中可见。
