Python calling raw_input from a subprocess

python, subprocess

Solution

Here's an example where the subprocess receives my input:

import subprocess
import sys

command = 'python -c \'print raw_input("Please make a selection: ")\''
sp = subprocess.Popen(command, shell = True, stdin = sys.stdin)
sp.wait()

Problem

I'm calling a python script from the below one using subprocess. From the command line the user chooses which file to open using raw_input ``` import optparse import subprocess import readline import os def main(): options = {'0': './option_0.py', '1': './option_1.py', '2': './option_2.py', '3': './option_3.py'} input = -1 while True: if input in options: file = options[input] subprocess.Popen(file) else: print "Welcome" print "0. option_0" print "1. option_1" print "2. option_2" print "3. option_3" input = raw_input("Please make a selection: ") if __name__ == '__main__': main() ``` However on the subprocess called(say option_1.py is called) I have a problem using raw_input again to accept prompt from the user. I am aware of the .PIPE arguments and have tried ``` subprocess.Popen(file, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) ``` But again no luck.
