I have a process id in Python. I know I can kill it with os.kill(), but how do I check if it is alive ? Is there a built-in function or do I have to go to the shell?

Use
subprocessmodule to spawn process.There is proc.poll() function – it returns
Noneif process is still alive, otherwise it returns process returncode.http://docs.python.org/library/subprocess.html
