Python3之线程Queue实现生产者消费者模型

生产者消费者模型

from threading import Threadimport queue, timeq = queue.Queue()def consumer():    while 1:        res = q.get()        time.sleep(2)        print('消费者消费了\033[35m%s\033[0m' % res)        q.task_done()def producer_0():    for i in range(5):        q.put(i)        print('生产者0生产了\033[35m%s\033[0m' % i)    q.join()def producer_1():    for i in range(5):        q.put(i)        print('生产者1生产了\033[32m%s\033[0m' % i)    q.join()def producer_2():    for i in range(5):        q.put(i)        print('生产者2生产了\033[33m%s\033[0m' % i)    q.join()if __name__ == '__main__':    t0 = Thread(target=producer_0, )    t1 = Thread(target=producer_1, )    t2 = Thread(target=producer_2, )    t0.start()    t1.start()    t2.start()    consumer_t = Thread(target=consumer, )    consumer_t.daemon = True    consumer_t.start()    t0.join()    t1.join()    t2.join()    print('主线程~')
