Capturing output with input

[gopala]

Hi, I am pretty new to python but i do have experience with c++. As a
part of learning exercise i wrote a python script to insert
beautifying comments(with name, problem...) to our lab program source
files (c language).

The script is working for most of the cases. The problem is i also
need to append the test output of the lab programs to the
corresponding source files(again the output should be added as a
beautified comment). The lab programs are interactive and very
different from each other. Currently in the script, i am prompting the
user(me!) to manually enter the output of the program which it to be
inserted. I want to eliminate this tedious step.

for eg i want "python commenter.py lab1.c" to initially prepend
comments with my name... and then spawn lab1.exe , capture its output
and append it with comments to lab1_com.c

My initial attempts of using spawn.. , exec.. pipe.. failed since they
can't capture the std input and std output continuously.
The lab1.exe will be something like

Enter 2 nos
2 3
The sum is 5

Now i should be able to capture all these.
Is this possible ? If so please do give me some hints on how to
achieve this.

Cheers,
Gopala Krishna

On Linux, use the "script" command.
On Windows, select the region to copy using the mouse and paste it onto a
notepad file.
I don't think Python would help here.

Thanks
Now i just do os.system(exeFile) and i can easily copy the output
from terminal using mouse selection.
