从线程返回值 [英] Return value from thread

问题描述

在Python中，如何获取线程以将元组或我选择的任何值返回给父级?

How do I get a thread to return a tuple or any value of my choice back to the parent in Python?

推荐答案

我建议您实例化

I suggest you instantiate a Queue.Queue before starting the thread, and pass it as one of the thread's args: before the thread finishes, it .puts the result on the queue it received as an argument. The parent can .get or .get_nowait it at will.

队列通常是在Python中安排线程同步和通信的最佳方法:队列本质上是线程安全的消息传递工具，通常是组织多任务的最佳方法！-)

Queues are generally the best way to arrange thread synchronization and communication in Python: they're intrinsically thread-safe, message-passing vehicles -- the best way to organize multitasking in general!-)
