#threading锁

本文详细介绍了Python中的四种线程同步工具：Lock、RLock、Semaphore和Condition，展示了它们在控制线程并发和通信中的应用，包括acquire(),release(),notify()和wait()方法。

import threading,time

lock=threading.Lock()
lock.acquire()
lock.release()


rlock=threading.RLock()
rlock.acquire()
rlock.release()


semaphore=threading.BoundedSemaphore(3)
semaphore.acquire()
semaphore.release()


clock=threading.Condition()
clock.acquire()
clock.release()
clock.notify()
clock.wait()

with lock:
    pass

with rlock:
    pass

with semaphore:
    pass

with clock:
    pass
