how to exit this loop in python

Question

why does break doesn't work? I want the code to stop when I click the specific key

import keyboard


def loop():
    x = 1
    while True:
        print(x)
        x = x+1


while True:
    if keyboard.is_pressed('q'):
        print("q pressed")
        break
    loop()

Answer 1

This is because you are in the function loop(). There is no break statement in the loop. Maybe try this?

import keyboard


def loop():
    x = 1
    while True:
        print(x)
        x = x+1
        if keyboard.is_pressed('q'):
            print("q pressed")
            break
    

      
loop()

Answer 2

This is because the break isn't inside the loop (function), to fix this we put the condition inside the desired loop.

import keyboard


def loop():
    x = 1
    while True:
        if keyboard.is_pressed('q'):
            print("q pressed")
            break
        print(x)
        x = x+1


while True:
    loop()

I presume the second loop is necessary, to not close the program.

Here you can just simply solve the error just by making 1 change.

Just delete the while True command in last when you call loop() function. That is the only thing that is causing an issue.

import keyboard
    
    def loop():
        x = 1
        while True:
            if keyboard.is_pressed("q"):
                print("\n q pressed")
                break
            print(x)
            x = x+1
    
    loop()

FYI: You can add some delay if you want counts to slow down. For that you will have to import time library.
