catching ctrl-c doesn't work

[lukaszrc]

while(1):
	try:
		#2 means port 2, onlineFollower means name of function handler
		bot.requestLineFollower(1,2,onLineFollower)
		print "!!!"
		sleep(0.5)
	except KeyboardInterrupt:
		print "stop!!!!!!!!!!!!!"
		input('Press enter to continue')_

It is not possible to print stop
I would like to stop motors somewhere
