How can I send a signal from a python program?

Question

I have this code which listens to USR1 signals

import signal
import os
import time

def receive_signal(signum, stack):
    print \'Received:\', signum

signa         


        

Answer 1

You can use os.kill():

os.kill(os.getpid(), signal.SIGUSR1)

Put this anywhere in your code that you want to send the signal from.
