Kill a python process

Question

I wrote a python script but accidentally put an infinite while loop in my script.

How do I kill the process? I've tried ctrl+c but with no success.

Are there any other option to try?

I'm on Mac Os X 10.7.2 with python 2.7

Try Ctrl+\ to send a SIGQUIT.

or

lsof -i :port

or 
sudo kill $(sudo lsof -t -i:8000)

ps a to get the PID of your process. kill -9 <pid> to send it the unblockable SIGKILL signal.

Note that I only have a Linux box in front of me to test, so the OS X commands may be slightly different.

worked perfectly thanks. Out of curiosity what is the -9 flag for? – Harpal Nov 09 '11 at 14:25

`SIGKILL` is signal number 9. `kill -X` is shorthand for `kill -s SIGNAME` if you don't want to type the symbolic name, and you know the number. I believe if you do `kill -l` (that's a lowercase L) it will list the signals and numbers on your system. – tdenniston Nov 09 '11 at 14:27

Open Activity monitor, go to the Processes tab, and highlight python.exe and quit it by clicking Quit.

this is maybe not the answer everyone likes, but it's still correct. You can use the activity monitor to kill it. – dwalter Sep 25 '20 at 18:15
