python 实现生产者 消费者案例

 

题目:python起2个进程一个为生产者、一个为消费者(消费者进程中起协程消费)

from multiprocessing import Process, Queue
import time
import random
import gevent


# 消费者方法
def consumer(q):
    while True:
        time.sleep(2)
        gevent_data_list = []
        gevent_data_list.append(gevent.spawn(pop_data, q))
        gevent.joinall(gevent_data_list)


def pop_data(q):
    res = q.get()
    print("消费了%s " % (res))


# 生产者方法
def producer(q):
    # for i in range(10):
    while True:
        time.sleep(1)
        number = random.randint(1, 10)
        print("生产了 %s" % (number))
        q.put(number)


if __name__ == "__main__":
    # 创建队列
    q = Queue()

    # 创建生产者
    p1 = Process(target=producer, args=(q,))
    c1 = Process(target=consumer, args=(q,))
    p1.start()
    c1.start()
