使用鍵偵聽器停止循環

Question

我試圖讓 python 運行一個循環，當我按Shift+a時循環停止：

import pyautogui
import time
import random
from pynput.mouse import Button, Controller
from pynput import keyboard

COMBINATIONS =[
    {keyboard.Key.shift, keyboard.KeyCode(char='a')},
    {keyboard.Key.shift, keyboard.KeyCode(char='A')}
    ]

on = True
print(on)

mouse = Controller()
curent = set()

def execute():
    on = False
    pass

def on_press(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        curent.add(key)
        if any(all(k in curent for k in COMBO) for COMBO in COMBINATIONS):
            execute()

def on_release(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        curent.remove(key)


with keyboard.Listener(on_press=on_press, on_release=on_release) as listner:
    listner.join()

execute()

time.sleep(4)
while on == True:
    print('hi')

問題是代碼甚至沒有到達：

with keyboard.Listener(on_press=on_press, on_release=on_release) as listner:
    listner.join()

如果我把它放在while True循環之后，快捷方式不起作用，它就會停止，如果我把它放在while True循環中，它會暫停循環。

Answer 1

您可以簡單地使用 add_hotkey 方法。 這是一個例子：

import keyboard

on = True

def execute():
    on = False # The function you want to execute to stop the loop

keyboard.add_hotkey("shift+a", execute) # add the hotkey

while on:
    print("hi") # Do the code of your loop here
