如何在记录器格式化程序中输入变量? [英] How to input variables in logger formatter?

问题描述

我目前有:

FORMAT = '%(asctime)s - %(levelname)s - %(message)s'
logging.basicConfig(format=FORMAT, datefmt='%d/%m/%Y %H:%M:%S', filename=LOGFILE, level=getattr(logging, options.loglevel.upper()))

...效果很好，但是我正在尝试做:

... which works great, however I'm trying to do:

FORMAT = '%(MYVAR)s %(asctime)s - %(levelname)s - %(message)s'

，即使定义了MYVAR，也只会引发键盘错误.

and that just throws keyerrors, even though MYVAR is defined.

有解决方法吗? MYVAR是一个常量，因此每次调用记录器时都必须传递它是一个可耻的事情.

Is there a workaround? MYVAR is a constant, so it would be a shame of having to pass it everytime I invoke the logger.

谢谢！
