How to stop a function & exit program running in a while loop on key press?

I need to stop a program when a keyboard key q is pressed how can i achieve in the below code how can i ignore time.sleep & detect a keypress & exit the program by printing something , currently the keypress gets detected only after 10 seconds suppose i am preesing q after 3 seconds the program doesnt exit

import sys
import time

import keyboard

def hd():
    print("Hi")
    time.sleep(10)
    if keyboard.is_pressed("q"):
        print(keyboard.is_pressed("q"))
        sys.exit()


while True:
    hd()

>Solution :

time.wait is a blocking call. Nothing happens in your program while it runs.

Shorten the intervals. For example, instead of sleeping 10 seconds, sleep 100 × 0.1 second.

import sys
import time

import keyboard

def hd():
    print("Hi")
    for _ in range(100):
        time.sleep(0.1)
        if keyboard.is_pressed("q"):
            print(keyboard.is_pressed("q"))
            sys.exit()

while True:
    hd()

For more complex behavior (doing actual work while also listening for a keyboard event) you will have to look into multithreading.
