python 信号量男上加男,Event发射set与等待wait有点Y

相当于游泳池，只能容纳3个猛男，所以是18个人抢3个游泳席位，3个人玩刺激哈哈

from  threading import Thread,Semaphore
s = Semaphore(3)
def run1(i):
        s.acquire()
        i=str(i)
        import time
        time.sleep(1)
        print("猛男{}正在大战".format(i))
        s.release()
if __name__ == '__main__':
    for i in range(18):
        t = Thread(target=run1,args=(i,))
        t.start()

效果如下

补充event

from threading import Event,Thread
e = Event()
def man_cry():
    print("ai")
    e.wait()

def woman_scream():
    e.set()
    print('aaaaaaaaaaaaa')

if __name__ == '__main__':
    for i in range(10):
        t = Thread(target=man_cry)
        t2 = Thread(target=woman_scream())
        t.start()
        t2.start()
