Python 队列

import queue,threading,time

def product(bq):
    str_tuple = ("Python","Kotlin","Swift")
    for i in range(9999):
        print(threading.current_thread().name+"生产者准备生产元素")
        time.sleep(0.2)
        bq.put(str_tuple[i % 3])
        print(threading.current_thread().name +"生产者生产元素完成")

def consume(bq):
    while True:
        print(threading.current_thread().name+"消费者准备消费元素")
        time.sleep(0.2)
        t = bq.get()
        print(threading.current_thread().name+"消费者消费【%s】元素完成！" %t)

#定义队列只容纳一个元素
bq = queue.Queue(maxsize=1)

threading.Thread(target=product,args=(bq,)).start()
threading.Thread(target=product,args=(bq,)).start()
threading.Thread(target=product,args=(bq,)).start()

threading.Thread(target=consume,args=(bq,)).start()
