[Tutor] using python to start and stop a program

[Joanna Ingrahm]

I have a program that I have to start using the win32
comand line. to stop it I use ctrl+c.
Now I tried to do that using python but still have
problems with it.
I can start the program and receive the pid of it
using: 

os.spawnl(os.P_NOWAIT,...

but then how can I use that information to terminate
the process again? I tried to write it in a file and
read it again but couldn't get it to work.
Appreciate any help!
