Subprocess.popen 返回奇怪的退出代码

Question

我对 subprocess.popen 有疑问。调用方法 ".poll()" 后创建的进程返回代码 "3221226505"

根据任务我需要运行多个 subprocess.popen 代码不会抛出异常。

if __name__ == "__main__":
    random_values = []
    processes = {}

    for i in range(10):
        random_value = random.randint(0, 100000)
        process = subprocess.Popen(["python3", "test.py"],
                                   env={"random_value": str(random_value)})
        random_values.append(random_value)
        processes[random_value] = process

    while True:
        for random_value in random_values:
            status_code = processes[random_value].poll()
            if status_code is not None:
                print(status_code)
                processes[random_value] = subprocess.Popen(["python3", "test.py"],
                                                           env={"random_value": str(random_value)})
            elif random_value not in processes:
                processes[random_value] = subprocess.Popen(["python3", "test.py"],
                                                           env={"random_value": str(random_value)})
            if processes[random_value].stdout:
                print(processes[random_value].stdout.readlines())
        time.sleep(1)

测试.py

if __name__ == "__main__":
    random_value= os.getenv("random_value")
    sys.stdout.write(random_value)
    sys.exit(0)
