import queue import time import random import threading import asyncio import logging logging.basicConfig(level = logging.INFO,format = ‘%(asctime)s - %(levelname)s -->%(funcName)s at line %(lineno)d: %(message)s‘) log= logging.getLogger() q_init = queue.Queue(maxsize=5) async def jobs(item): time.sleep(random.randint(1,15)) status = random.randint(0, 1) if status == 0: return ("success",item) else: return ("failed",item) async def do_work(item): logging.info("do something %s,time start %s" % (item, time.asctime())) a =await jobs(item) return a def ma(checker): new_loop = asyncio.new_event_loop() asyncio.set_event_loop(new_loop) loop = asyncio.get_event_loop() task = asyncio.ensure_future(do_work(checker)) loop.run_until_complete(asyncio.wait([task])) st = task.result() print(st) return st def worker_consumer(q_init): while True: if q_init.empty(): logging.info("queue is empty stop current thread worker by break " ) break checker = q_init.get() st=ma(checker) if st[0] in ["success", "failed"]: logging.info("%s task finished status is %s" % (st[1],st[0])) q_init.task_done() def producer(): item = 1 while item: q_init.put(item) item += 1 if item > 50: break if __name__ == ‘__main__‘: producer = [threading.Thread(target=producer)] consumer = [threading.Thread(target=worker_consumer, args=(q_init,)) for i in range(5)] consumer_pool = [] p_pool=[] for p in producer: p.start() for k in consumer: k.start() consumer_pool.append(k) for m in consumer: m.join() q_init.join()
结果：
