使用Python与正在运行的控制台应用程序进行交互

Question

On my system, I have an already-running console application that receives commands and emits output accordingly. I would like to connect to this application from a python script, and interact with it. Is it possible?

I know I cannot use subprocess or similar because they just launch another process; I need to talk to an already existing one. How can I do it, in detail? Do I need to set up pipes, or sockets? What's the best way to do it?

Answer 1

If I understand your question correctly, you might want a tool like reptyr that can re-assign the pty of the process in which you're interested.

You might also investigate the answer to this question that is similar.

Once you have the pty, then you can either use pexpect to handle the interaction.
