help with popen, one-way IPC.

[Brian Alexander]

Hello;

I have a program that might possibly be writing to stdout (not a python
program) and would like to use redirection in Python to collected the
output. I'm having a little trouble with the call to popen(), though.

I thought it was this:

otherapp_stdout = popen( "appname", "r")

while otherapp_stdout.readline != "\n"
    # do stuff with each line.

Is this the right idea. Communication only needs to be one way.

Many thanks in advance,

Brian.
