Question

我想使用脚本来调用可执行程序并在exe程序（DOS窗口）中输入一些指令来运行这个exe程序（不需要输出）

例如，如果我直接运行该程序，我将双击它并键入如下：

load XXX.txt
oper
quit

这是我的代码，fwiw我对子进程没有深刻的理解。

import subprocess
import os
os.chdir('D:/Design/avl3.35/Avl/Runs')
Process=subprocess.Popen(['avl.exe'], stdin=subprocess.PIPE)
Process.communicate(b'load allegro.avl\n')

当我运行此代码时，我得到以下内容：

我不知道这有什么问题，我也不知道为什么错误提示会显示在代码中。搜索后我发现communicate方法是等待进程完成并返回所有输出，虽然我不需要输出，但我仍然不知道该怎么做。

你能解释一下这里发生了什么，我怎么能完成我想做的事情？

Python用输入运行.exe
