当python使用"Python.h“调用c++进程时，如何在python中停止c++进程

import os

# 停止C++进程的函数
def stop_cpp_process(process_id):
    command = "kill -9 {}".format(process_id)
    os.system(command)

# 调用停止C++进程的函数
stop_cpp_process(12345)  # 传入C++进程的ID

import subprocess

# 启动C++进程的函数
def start_cpp_process():
    process = subprocess.Popen(["./cpp_program"], stdout=subprocess.PIPE)
    return process

# 停止C++进程的函数
def stop_cpp_process(process):
    process.terminate()

# 调用启动和停止C++进程的函数
cpp_process = start_cpp_process()
# 执行其他操作...
stop_cpp_process(cpp_process)
