Do basic configuration for the logging system.:对记录系统进行基本配置。 This function does nothing if the root logger already has handlers configured, unless the keyword argument *force* is set to ``True``.:如果根记录器已经有了处理程序,这个函数什么也不做除非关键字参数force设置为“True”。 A ...

one way of doing this is to have all the processes log to a SocketHandler, and have a separate process which implements a socket server which reads from the socket and logs to file. (If you prefer, you can dedicate one thread in one of the existing processes to perform this function.)...
