我最近开始使用 python，并且对这个主题相当陌生。目前，我正在开发一个项目，该项目将根据屏幕上的特定像素值模拟键盘按下。基本上，如果“这样的像素”被着色为“这样的颜色”，然后单击/按下。但是，我的代码有一个错误。有时，它运行得很好，但随后随机停止运行。其他时候，它根本不运行。在这两种情况下，都会出现错误（如下代码）。这是我当前的代码：

import random
import time

import keyboard
import pyautogui
import win32api
import win32con
from pyautogui import *
from pynput.keyboard import Key, Controller


simulate = Controller()


def click(x, y):
    win32api.SetCursorPos((x, y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0, 0)


def jump():
    simulate.press(Key.up)
    simulate.release(Key.up)
    click(650, 540)
    print("Jumped!")


def duck():
    simulate.press(Key.down)
    simulate.release(Key.down)
    print("Ducked!")


def restart():
    click(950, 500)


def switch():
    simulate.press(Key.alt)
    simulate.press(Key.tab)
    simulate.release(Key.alt)
    simulate.release(Key.tab)


def play():
    while not keyboard.is_pressed('a'):
        if pyautogui.pixel(660, 540)[0] != 247:
            jump()

        if pyautogui.pixel(950, 500)[0] == 83:
            restart()


switch()
play()
switch()

这是控制台：

Traceback (most recent call last):
  File "C:...\main.py", line 59, in <module>
    play()
  File "C:...\main.py", line 51, in play
    if pyautogui.pixel(660, 540)[0] != 247:
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\pyscreeze\__init__.py", line 584, in pixel
    return (r, g, b)
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\contextlib.py", line 124, in __exit__
    next(self.gen)
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\pyscreeze\__init__.py", line 113, in __win32_openDC
    raise WindowsError("windll.user32.ReleaseDC failed : return 0")
OSError: windll.user32.ReleaseDC failed : return 0

Process finished with exit code 1

为什么这段代码有时只工作，然后随机停止？是下载或导入的问题，还是其他问题？如果您能提供帮助，将不胜感激。谢谢！
