How to find PID by application name using shell command [duplicate]

Question

I started a python program and send it to the background.

$: python myapp.py &

Then I closed the terminal and forgot the PID it returned. Now I would like to kill that program, the only clue I left is the program name myapp.py. How can I find the PID using shell command?

First way:
Try ps -ef | grep myapp.py to find the PID, Then kill it.

Another way is:
Try pkill -f myapp.py to kill it by its name.
