我只想要StreamHandler生成的日志,但是由于某种原因,一切都被记录了两次。格式化root logger似乎也不起作用。
我已经搜索了日志记录文档,并试图找出问题所在,但似乎找不到与我的问题相关的任何内容。我也尝试了几种不同的设置,但找不到任何有效的方法。
这是我尝试过的最新内容:
logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
stream_handler = logging.StreamHandler()
stream_handler.setFormatter(formatter)
logger.addHandler(stream_handler)
logger.info('Modeling for date %s, saving outputs %s', date_string, save_loc_str)
输出:
2019-10-17 14:20:47,547 - __main__ - INFO - Modeling for date 2019-10-17, saving outputs to S3
INFO:__main__:Modeling for date 2019-10-17, saving outputs to S3
我也尝试过简单地在basicConfig中更改格式,但是该格式没有更新:
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
logger.info('Modeling for date %s, saving outputs %s', date_string, save_loc_str)
输出:
INFO:__main__:Modeling for date 2019-10-17, saving outputs to S3
简单
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)
logging.info('Modeling for date %s, saving outputs %s', date_string, save_loc_str)
也将不起作用,并提供与先前的输出相同的输出:/
