Use pkill command as

pkill -f test.py

(or) a more fool-proof way using pgrep to search for the actual process-id

kill $(pgrep -f 'python test.py')

Or if more than one instance of the running program is identified and all of them needs to be killed, use killall(1) on Linux and BSD

killall test.py
