The background processes are run one time, and after that, they are automatically processed when we start a computer, and they stop when we turn off our computer. We can also stop background processes by going to the task manager or using the Python command to kill the process using its...

The background thread will quit once it has flushed all buffered data to the pipe. 当队列被垃圾回收时,这被自动调用。"""join_thread()"""加入后台线程。这只能在调用close()之后使用。它阻塞直到后台线程退出,确保缓冲区中的所有数据都已刷新到pipe。
