Hi,
I am very new to python. I have my cgi script written in Python. My
CGI script should call a C program and collect the value returned by
this program and pass it to the browser.
Can anyone help me out in this. How can I execute the c program and
collect the return value.
I tried,
import os
a=os.system("my-app")//my-app is the C program executable
print a
But the variable *a* prints 0 everytime. It should return a non-zero
value as per my C program. Is there any method to do what I need.
Regards,
vish

Executing from os.system returns the return code from the application.
Take a look at the subprocess module
(http://docs.python.org/library/subprocess.html#module-subprocess), as
recommended by the os docs when you need to deal with capturing output
from stdout.
