raw_input() simulation

[Martynas Jocius]

Hello,

Here is the backend:

# backend.py
str = raw_input("") # or some analog
print str

And here is the frontend:

# frontend.py
import popen2

fout, fin = popen2.popen2("python backend.py")

Now I want to send to my backend some text and read the output from it.
fout.read() works for output, but, for example, fin.write("test\n") doesn't
work, maybe beacuse it left to "press" <Enter> in a raw input. Is there any
way to simulate input from a keyboard? Couldn't find any example on the net.
Thanks.
