F-strings are the clear winner in terms of readability. However, they don’t allow you to do lazy interpolation. There’s no way to use an f-string to create a reusable string template that you can interpolate later in your code. If you want a universal tool with all the features, th...
from loguru import loggerlogger.debug("That's it, beautiful andsimple logging!") [2] 无需初始化,导入函数即可使用 如何添加处理程序(handler)呢? 如何设置日志格式(logs formatting)呢? 如何过滤消息(filter messages)呢? 如何如何设置级别(log level)呢?
loguru与logging对比 使用Python 来写程序或者脚本的话,常常遇到的问题就是需要对日志进行删除。一方面可以帮助我们在程序出问题的时候排除问题,二来可以帮助我们记录需要关注的信息。 如果使用自带自带的logging模块的话,则需要我们进行不同的初始化等相关工作。对应不熟悉该模块的伙伴们来说还是有些费劲的,比如需要配置...
