Python是否具有与Java的CountDownLatch类似的控制机制？

import threading

def worker(barrier):
    print("等待其他线程...")
    barrier.wait()
    print("所有线程已经同步，继续执行...")

num_threads = 5
barrier = threading.Barrier(num_threads)

threads = []
for i in range(num_threads):
    t = threading.Thread(target=worker, args=(barrier,))
    threads.append(t)
    t.start()

for t in threads:
    t.join()
