Blink an LED connected to a Raspberry Pi, and interrupt it with the keyboard

import time

import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BOARD)

GPIO.setup(11, GPIO.OUT)


def wait_for_input(stop):
    input("Press enter to stop blinking.")
    stop.append(True)
    print("Stopping the blinking.")

def blink():
    stop = []
    _thread.start_new_thread(wait_for_input, (stop,))
    while True:
        GPIO.output(11, True)
        time.sleep(2)
        GPIO.output(11, False)
        time.sleep(2)
        if stop: break

blink()

GPIO.cleanup()

Your saving my life with this code. Thanks!
