subprocess - Interact with executables over server in Python? -

i want run executable on tcp server , take input socket connections interactively , send output client until executable terminated. trying piping through popen class of subprocess not helping interaction executable ( take input 1 time want input taken time until program exits ).

suppose send "1" input server server must send stdout corresponding "1" input client , ask next input , till executable exits in continuation .

just provide socket standard input, output, , error of subprocess. e.g.:

import socket import subprocess  listener = socket.socket(socket.af_inet, socket.sock_stream) listener.setsockopt(socket.sol_socket, socket.so_reuseaddr, true) listener.bind(('0.0.0.0', 0)) listener.listen(5) print(listener.getsockname())  try:     while true:         client, addr = listener.accept()         subprocess.popen(['cat'], stdin=client, stdout=client, stderr=client)         client.close() except keyboardinterrupt:     pass finally:     listener.close() 

this requires posix-compliant operating system.
