如何退出使用python脚本pyhook使用快捷键？

这是我打算做的一个可以自动粘贴到聊天窗口并用鼠标点击发送的小脚本

但是，此脚本只能运行到运行后才能停止

我的问题是如何设置快捷键（如F12）您可以按F12停止脚本

脚本代码如下：

# _*_ coding:UTF-8 _*_
import win32api
import win32con
import win32gui
from ctypes import *
import time
import msvcrt
import threading
from time import sleep

stop = 2
def mouse_click(x=None,y=None):
    if not x is None and not y is None:
        mouse_move(x,y)
        time.sleep(0.05)
        win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)     
        win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)   
def mouse_move(x,y):
    windll.user32.SetCursorPos(x, y)

def baozou():
    global stop
for event in range(1,50):
    mouse_click(1150,665)
    win32api.keybd_event(17,0,0,0)  
    win32api.keybd_event(86,0,0,0)  
    win32api.keybd_event(86,0,win32con.KEYEVENTF_KEYUP,0) 
    win32api.keybd_event(17,0,win32con.KEYEVENTF_KEYUP,0) 
    mouse_click(1272,669)
    time.sleep(0.1)
    if stop == 1:
        sys.exit()

def Break():
    global stop
    if ord(msvcrt.getch()) == 123:
        stop = 1

if __name__ == "__main__":
    t = threading.Thread(target = baozou)
    f = threading.Thread(target = Break)
    t.start()
    f.start()

请帮我一把

我已经设法解决了这个问题，我的工作代码是：
