The ps command will usually give you a list of the running processes with
their argument, but using that is suboptimal.

I suppose you start the process in the background, like: python myscript &.
When you start the python script in bash (or any other process for that
matter) in the background you can get the process id (pid) with $!
(immediately after starting the process). Later on you can use this to kill
the process:

python myscript myargs &
savepid=$!


later: kill $savepid

That is much better than trying to grep through the ps output.
