Stop my code when pressing keyboard button

Question

my problem is when i press "p" code not stopping. I have to spam "p" for stopping code, probably there is time.sleep and i have to wait for it but i cant wait for it. I want to stop code immediately when i press p. is there any way for it ? there is my code

import pyautogui as pg
import keyboard
import time
from PIL import Image

button = "p"

def m():
    if pg.locateOnScreen('Screenshot_2.png', confidence = 0.9):
        pc = pg.locateOnScreen('Screenshot_2.png', confidence = 0.9)
        pg.center(pc)
        pg.click(pc)
        print('found!')
        time.sleep(2)
    else:
        time.sleep(3)
        print('not found!')
        
        
while True:
    m()
    if keyboard.is_pressed(button):
        print("stopped")
        break

Because it's checking if the key is pressed in the exact moment that if statement is executed. Which is a problem when that loop is spinning so fast. You can use a callback to essentially cache the should stop condition.

import pyautogui as pg
import keyboard
import time
from PIL import Image

button = "p"

stop = False
def onkeypress(event):
    global stop
    if event.name == button:
        stop = True

def m():
    if pg.locateOnScreen('Screenshot_2.png', confidence = 0.9):
        pc = pg.locateOnScreen('Screenshot_2.png', confidence = 0.9)
        pg.center(pc)
        pg.click(pc)
        print('found!')
        time.sleep(2)
    else:
        time.sleep(3)
        print('not found!')
        
      
keyboard.on_press(onkeypress)  
while True:
    m()
    if stop:
        print("stopped")
        break
