如何在Python中禁用和重新启用控制台日志记录? [英] How to disable and re-enable console logging in Python?

问题描述

我正在使用Python的日志记录模块，并且我想禁用某些控制台记录时间，但不起作用.

I am using Python's logging module and I want to disable the console logging for some time but it doesn't work.

#!/usr/bin/python
import logging

logger = logging.getLogger() # this gets the root logger
# ... here I add my own handlers 
#logger.removeHandler(sys.stdout)
#logger.removeHandler(sys.stderr)

print logger.handlers 
# this will print [<logging.StreamHandler instance at ...>]
# but I may have other handlers there that I want to keep

logger.debug("bla bla")

上面的代码在stdout上显示bla bla，我不知道如何安全地禁用控制台处理程序.如何确定我暂时删除了控制台StreamHandler而不是另一个?

The above code displays the bla bla on stdout and I don't know how can I safely disable the console handler. How can I be sure that I temporarily remove the console StreamHandler and not another one?

推荐答案

我为此找到了解决方案:

I found a solution for this:

logger = logging.getLogger('my-logger')
logger.propagate = False
# now if you use logger it will not log to console.

这将防止日志发送到包含控制台日志的上层日志.

This will prevent logging from being send to the upper logger that includes the console logging.
