import multiprocessing

def sender(queue):
    queue.put('hello')

def receiver(queue):
    msg = queue.get()
    print('received:', msg)

if __name__ == '__main__':
    queue = multiprocessing.Queue()
    p1 = multiprocessing.Process(target=sender, args=(queue,))
    p2 = multiprocessing.Process(target=receiver, args=(queue,))
    p1.start()
    p2.start()
    p1.join()
    p2.join()
