# This sets the root logger to write to stdout (your console). # Your script/app needs to call this somewhere at least once. logging.basicConfig() # By default the root logger is set to WARNING and all loggers you define # inherit that value. Here we set the root logger to NOTSET....
logging.getLogger([name])方法返回一个Logger实例的引用,如果提供了name参数,那么它就是这个Logger实例的名称,如果没提供name参数,那么这个Logger实例的名称是root。可以通过Logger实例的name属性,来查看Logger实例的名称。Logger实例的名称是使用句号(.)分隔的多级结构。在这种命名方式中,后面的logger是前面的logger的子(...

In addition to making the code more readable, Timer takes care of printing the elapsed time to the console, which makes the logging of time spent more consistent. When you run the code, you’ll get pretty much the same output: Shell $ python latest_tutorial.py Elapsed time: 0.6462 ...
It will not work simultaneously for multiple handlers at a time, i.e., you can’t use both console or file simultaneously for logging; It doesn’t allow different configurations for different severity levels. For these reasons, it is recommended to configure the root logger but to avoid using...
