How to stop code from executing code by successively pressing ctrl + c keys without calling KeyboardInterrupt?

Question

Python

import keyboard
import time
def waiting():
    curtime = time.perf_counter()
    while (time.perf_counter() - curtime) <= 2:
        keyboard.add_hotkey('Ctrl + c', exit())
    cycle()
def cycle():
    while True:
        try:
            keyboard.add_hotkey('Ctrl + c', lambda: print('Hello'))
        except KeyboardInterrupt:
            waiting()
cycle()

It is necessary that the first time you press Ctrl + C, a message is displayed, but the code does not stop,
and if after pressing CTRL + C, CTRL + C is pressed again for 2 seconds, then the code execution
stops, while the program runs indefinitely
