Return value from thread

You should pass a Queue instance as a parameter then you should .put() your return object into the queue. You can gather the return value via queue.get() whatever object you put.

Sample:

queue = Queue.Queue()
thread_ = threading.Thread(
                target=target_method,
                name="Thread1",
                args=[params, queue],
                )
thread_.start()
thread_.join()
queue.get()

def target_method(self, params, queue):
 """
 Some operations right here
 """
 your_return = "Whatever your object is"
 queue.put(your_return)

Use for multiple threads:

#Start all threads in thread pool
    for thread in pool:
        thread.start()
        response = queue.get()
        thread_results.append(response)

#Kill all threads
    for thread in pool:
        thread.join()

I use this implementation and it works great for me. I wish you do so.

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.

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!-)
