Loggerobjects have a threefold job. First, they expose several methods to application code so that applications can log messages at runtime. Second, logger objects determine which log messages to act upon based upon severity (the default filtering facility) or filter objects. Third, logger objects...
你会发现Info的信息并没有打印出来,这是因为logging 默认的Level是warning,只有在比warning更严重的message才会打印出来。 logging模块中各个Level日志级别关系为:CRITICAL > ERROR > WARNING > INFO > DEBUG > NOTSET,当然也可以自定义。 logging to file 一个简单的例子 import logging logging.basicConfig(filename=...

logging是模块名。 logging模块是Python内置的标准模块。 内置模块直接导入即可使用,不需要安装。 【导入语法】 import+模块名 【代码示例】 import logging 4. 日志的5种级别 开发者根据事件的重要性对程序日志进行了等级划分。 我们可以通过函数、参数等确定输出的日志等级。
