Just like it’s hard to find a simple stopwatch application, it can be hard to find a simple countdown application. Let’s write a countdown program that plays an alarm at the end of the countdown.
At a high level, here’s what your program will do:
- Count down from 60
- Play a sound file (alarm.wav) when the countdown reaches zero
A countdown is a simple delay before continuing the program’s execution. This can also be used for other applications and features, such as the following:
- Use
time.sleep()to give the user a chance to press CTRL-C to cancel an action, such as deleting files. Your program can print a “Press CTRL-C to cancel” message and then handle any KeyboardInterrupt exceptions with try and except statements - For a long-term countdown, you can use timedelta objects to measure the number of days, hours, minutes, and seconds until some point (a birthday? an anniversary?) in the future
