Question

in python:

The timer module provides a sleep() function to cause a delay of a specified time. Use this function to write a function countdown(n), which counts down from a given non-negative integer n to 0, one step each second. Use try and except in such a way that the countdown cannot be stopped by pressing Ctrl-C.

Answer 1

def countdown1(n):
    try:
        while n >= 0:
            try:
                time.sleep(1)
                print(n)
                n -= 1
            except(KeyboardInterrupt):
                pass
    except():
        pass


countdown1(10)
