如何确定通过Python (理想情况下使用子进程)运行的程序是否崩溃或成功结束

import subprocess

process = subprocess.Popen(['python', 'program.py'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

while process.poll() is None:
    # 子进程仍在运行
    pass

exit_code = process.poll()

import subprocess

def run_program():
    process = subprocess.Popen(['python', 'program.py'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    
    while process.poll() is None:
        # 子进程仍在运行
        pass
    
    exit_code = process.poll()
    
    if exit_code == 0:
        print("程序成功结束")
    else:
        print("程序崩溃或发生错误")

run_program()
