生产者消费者模型的一个问题

from multiprocessing import Process, Queue, JoinableQueue


def consumer(q, name):
    while 1:
        info = q.get()

        print("%s吃了" % name + info)

        q.task_done()


def producer(q, name):
    for i in range(10):
        info = '%s生产了%s号包子' % (name, i)
        q.put(info)
    q.join()


if __name__ == '__main__':
    q = JoinableQueue(10)
    pro = Process(target=producer, args=(q, 'Tom',))
    con = Process(target=consumer, args=(q, 'Jake'))
    con.daemon = True
    pro.start()
    con.start()
    pro.join()

# from multiprocessing import Process, JoinableQueue
# import time
# import random

# def producer(q, product):
#
#     for i in range(1, 11):
#         info = '%s %s' % (product, i)
#         q.put(info)
#
#
# def consumer(q, name):
#     #time.sleep(0.5)
#     while 1:
#         info = q.get()
#         print('%s消费了%s' % (name, info))
#
#
# if __name__ == '__main__':
#     q = JoinableQueue()
#     pp = Process(target=producer, args=(q, '烤面筋'))
#     pc1 = Process(target=consumer, args=(q, 'jason'))
#     pc1.daemon = True
#     pc1.start()
#     pp.start()
#     pp.join()

#之所以会这样，是因为电脑执行太快了，做的快消费的也快，如果做的快消费的慢，那么将不会消费！这与计算机执行快慢有关系。
