logger.setLevel(logging.DEBUG) # If that prints too much, enable debug printing only for your component: component_logger.setLevel(logging.DEBUG) # For production you rather want: logger.setLevel(logging.WARNING) 一个常见的混淆源来自一个错误初始化的根记录器。考虑一下: import logging log = loggi...
其中,emit(record)方法负责执行真正地记录日志所需的一切事情,在logging.Handler的子类中必须实现这个方法。close()方法负责清理handler所使用的资源(在Python解释器退出的时候,会调用所有的handler的flush()和close()方法),logging.Handler的子类应该确保在重写close()方法的时候,调用父类的该方法。 下面分析logging.Strea...

Note that the order in which the inner functions are defined does not matter. Like with any other functions, the printing only happens when the inner functions are executed.Furthermore, the inner functions aren’t defined until the parent function is called. They’re locally scoped to parent(...

Benefits of LoggingYou may ask: “Why not just use printing?”When you run an algorithm and want to confirm it is doing what you expected, it is natural to add some print() statements at strategic locations to show the program’s state. Printing can help debug simpler scripts, but as ...
