process - How to kill Python Multiprocessing.Pool by pid?

Question

import multiprocessing
import os
import time


def work():
    pid, ppid = os.getpid(), os.getppid()
    print('pid={}, ppid={}'.format(pid, ppid))
    time.sleep(10)


def run_process(n):
    pool = multiprocessing.Pool(10)

    res_l = []
    for _ in range(n):
        res = pool.apply_async(work)
        res_l.append(res)

    pool.close()
    pool.join()

run_process(2)

pid_0=63780, ppid=63779 pid_1=63781, ppid=63779

I have to kill pid and ppid to kill the current process.Is there a better way？Or I just want to one of the subprocesses. What should I do?

def kill_proc(pid, ppid):
    os.kill(pid, signal.SIGTERM)
    os.kill(ppid, signal.SIGTERM)
