python catch kill signal

signal.py

#We can check for Ctrl-C with KeyboardInterrupt exception as follows:

try:
    while True:
        print "Echo ", raw_input(">")
except KeyboardInterrupt:
    print "Good bye"

#When python process was killed, we will not get KeyboardInterrupt. But we can instead catch SIGTERM sent by kill command.
#In order to catch SIGTERM, we can do:


import signal
import sys
 
def signal_term_handler(signal, frame):
    print 'got SIGTERM'
    sys.exit(0)
 
signal.signal(signal.SIGTERM, signal_term_handler)

#List of signal is available in POSIX Signals. Note that SIGKILL cannot be caught.
