Timer stops before I type the exit code Python

[Enderg312]

<

import time
import winsound

def countdown(t):
    while t:
        mins, secs, = divmod(t, 60)
        timer = '{:02d}:{:02d}'.format(mins, secs)
        print(timer, end="\n")
        time.sleep(1)
        t -= 1

    print('Timer completed!')

t = input('Enter the time in seconds: ')

def beep():
    winsound.Beep(700, 1000)
    time.sleep(0.75)

countdown(int(t))
while True:
    beep()

    if input() == "stop":
        exit()

This is meant to constantly beep but it only beeps once and if I take the if statement away it constantly beeps, how can I get it to constantly beep with the exit code?

countdown(int(t)) will run its entire loop before the 'while True:' loop is run.

Your program asks for a time in seconds, counts down from that time, then beeps once and exits. This is like a kitchen timer program - set the time, then get a beep at the end.

 

By "constantly beep" do you mean to start beeping as soon as you begin the program? If so, you'd do better to put it inside the timer loop.

It's a timer, constantly beep after the time hits zero.

You'd need to spawn a separate thread or process that beeps.

It does beep I want to make a exit code that ends the beeping after the user knows the timer is going off.

if you use sleep in your main process, the process will sleep for 1s and you won't do anything with your input.

 

Look into async  stuff :  https://stackoverflow.com/questions/45419723/python-timer-with-asyncio-coroutine

 

// not a Python programmer but I'm familiar with the concept from other programming languages (ex javascript, microcontroller interrupts etc)

Yes, that's why you would use separate threads for the beep and the main loop, for example. Currently that while loop will just beep, check for input, beep if input is not stop, check for input etc. A separate thread will run independent from the main loop and will allow you to beep while checking for the input to be stop. The threading module will allow you to create separate threads (but still limited on the same core) and multiprocessing, for example, will allow you to leverage multiple cores by spawning a new process.

 

If you're on Python 3.7 you may also try the above suggestion using asyncio (I acutally didn't know about this one yet, it seems pretty neat).
