kill subprocess when python process is killed?

Question

I am writing a python program that lauches a subprocess (using Popen). I am reading stdout of the subprocess, doing some filtering, and writing to stdout of main process.

Windows doesn't have signals, so you can't use the signal module. However, you can still catch the KeyboardInterrupt exception when Ctrl-C is pressed.

Something like this should get you going:

import subprocess

try:
    child = subprocess.Popen(blah)
    child.wait() 

except KeyboardInterrupt:
    child.terminate()
