Logging in Python works by configuring loggers and setting log levels. Using a logging library provides structured logging and control over log output. You should prefer logging over print() because it decreases the maintainance burden and allows you to manage log levels.You...

3. Logging 导入 Logging模块是Python的内置模块,所以我们无需再显示进行安装。如果我们想要使用该模块,可以直接使用以下语句: importlogging 其中,Logging模块有很多内容,但是今天主要分享一个基础例子和一个高级例子供大家学习。 4. Logging Levels 日志记录级别(Logging Levels)允许我们设置更加具体的输出日志等级,例如调...
levels = [logging.DEBUG, logging.INFO, logging.WARNING, logging.ERROR, logging.CRITICAL] loggers = ['foo', 'foo.bar', 'foo.bar.baz', 'spam', 'spam.ham', 'spam.ham.eggs'] for i in range(100): lv1=l = random.choice(levles) logger = logging.getLogger(random.choice(loggers)) lo...
Logging Levels 共有几个等级, 每个等级对应一个Int 型整数 ,每个等级都会有一个方法与之对应,这样输出的内容就有了不同的等级. logger 流程, 整个过程,还是不是很详细,贴个图吧, 现在看还太早,也说不清真个过程到底发生了什么,先放着,回头来看会比较好懂. loger flow ...
