我见过类似的问题:keep multiple console windows open from batch。
但是,我有不同的情况。我不想在不同的控制台窗口中运行不同的脚本。我的想法是将套接字作为服务器运行并接受所有连接。接受连接后,将创建一个新的控制台窗口,并显示所有正在进行和即将进行的数据。这甚至可能吗?
答案 0 :(得分:2)
进程一次只能附加到一个控制台(即conhost.exe的实例),并且没有附加进程的控制台会自动关闭。您需要使用creationflags=CREATE_NEW_CONSOLE
生成子进程。
以下演示脚本需要Windows Python 3.3+。它产生两个工作进程,并通过socket.share
和socket.fromshare
将每个套接字连接复制到工作程序中。封送的套接字信息通过管道发送给孩子的stdin
。加载套接字连接后,管道关闭,CONIN$
打开为sys.stdin
,以从控制台读取标准输入。
