Redirecting stdout to another script

[=?ISO-8859-1?Q?Richard_Sim=F5es?=]

Hopefully, this explanation will sufficiently clear despite the lack
of code.

I wrote a python script that takes data via stdin, does stuff with the
data, and outputs the result to stdout. A friend wrote a perl script
that opens a pipe to my script, feeds it data, and then accepts the
result. The problem here is that the python script's outputting the
result to stdout via print statements isn't doing what we expected: my
friend's perl script isn't getting the result back via the pipe.

Is there is simple solution for this problem? Whose script needs to be
modified?

Thanks,
Richard Simões

That of your friend, if he is the one invoking you. Because the invoking
script is the one responsible for connecting the pipes properly.
