如何在python龙卷风中使用日志记录并写入文件

Question

Currently I'm using logging.getLogger().setLevel(logging.DEBUG) what I think is logging everything where logging level is => DEBUG Is that a correct assumption? I can see a difference when I set logging.DEBUG to logging.ERROR so I guess I'm correct.

Also how do I write these logging rows to a file?

Answer 1

This is a exmaple write log to file

import logging

logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)

# create a file handler

handler = logging.FileHandler('hello.log')
handler.setLevel(logging.INFO)

# create a logging format

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)

# add the handlers to the logger

logger.addHandler(handler)

logger.info('Hello baby')
