python进程锁

标签：线程   __name__   release   sleep   ESS   rgs   targe   multi   import   

import time
import threading
import multiprocessing
lock = multiprocessing.RLock()
def task(arg):
    print('进程来了')
    lock.acquire()
    time.sleep(2)
    print(arg)
    lock.release()
if __name__ == '__main__':
    p1 = multiprocessing.Process(target=task,args=(1,))
    p1.start()

    p2 = multiprocessing.Process(target=task, args=(2,))
    p2.start()  

和线程锁一样,对照线程锁学习即可
