如何在运行完整脚本的python中停止多进程

import multiprocessing
import time

def worker():
    while True:
        print("Working...")
        time.sleep(1)

if __name__ == "__main__":
    process = multiprocessing.Process(target=worker)
    process.start()
    time.sleep(5)  # 运行5秒后停止子进程
    process.terminate()

import multiprocessing
import time

def worker(index):
    while True:
        print(f"Working in process {index}...")
        time.sleep(1)

if __name__ == "__main__":
    pool = multiprocessing.Pool(processes=4)
    for i in range(4):
        pool.apply_async(worker, args=(i,))
    time.sleep(5)  # 运行5秒后停止所有子进程
    pool.terminate()
