python_多线程加锁

import time, threading
count=0 #声明全局变量
lock=threading.Lock() #申请一把锁
def lajifenlei():
    global count #引用全局变量
    lock.acquire()  #加锁
    count+=1
    lock.release() #释放锁
    time.sleep(1)
    print(count)

for i in range(10):
    th = threading.Thread(target=lajifenlei,) #声明线程数
    th.start() #启动线程
while threading.activeCount()!=1:
    pass
