帮我用python编一个弹窗贪吃蛇游戏

当然可以帮您编写一个弹窗贪吃蛇游戏。以下是一个简单的示例代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义常量
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600
SNAKE_SIZE = 20
SNAKE_SPEED = 10
APPLE_SIZE = 20

# 定义颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)

# 创建窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("贪吃蛇游戏")

# 定义贪吃蛇类
class Snake:
    def __init__(self):
        self.length = 1
        self.positions = [((WINDOW_WIDTH // 2), (WINDOW_HEIGHT // 2))]
        self.direction = random.choice([pygame.K_UP, pygame.K_DOWN, pygame.K_LEFT, pygame.K_RIGHT])
        self.color = RED

    def get_head_position(self):
        return self.positions[0]

    def move(self):
        cur = self.get_head_position()
        x, y = self.direction
        new = (((cur[0] + (x * SNAKE_SIZE)) % WINDOW_WIDTH), (cur[1] + (y * SNAKE_SIZE)) % WINDOW_HEIGHT)
        if len(self.positions) > 2 and new in self.positions[2:]:
            self.reset()
        else:
            self.positions.insert(0, new)
            if len(self.positions) > self.length:
                self.positions.pop()

    def reset(self):
        self.length = 1
        self.positions = [((WINDOW_WIDTH // 2), (WINDOW_HEIGHT // 2))]
        self.direction = random.choice([pygame.K_UP, pygame.K_DOWN, pygame.K_LEFT, pygame.K_RIGHT])

    def draw(self, surface):
        for p in self.positions:
            pygame.draw.rect(surface, self.color, (p[0], p[1], SNAKE_SIZE, SNAKE_SIZE))

# 定义苹果类
class Apple:
    def __init__(self):
        self.position = (0, 0)
        self.color = RED
        self.randomize_position()

    def randomize_position(self):
        self.position = (random.randint(0, (WINDOW_WIDTH - APPLE_SIZE) // APPLE_SIZE) * APPLE_SIZE, 
                         random.randint(0, (WINDOW_HEIGHT - APPLE_SIZE) // APPLE_SIZE) * APPLE_SIZE)

    def draw(self, surface):
        pygame.draw.rect(surface, self.color, (self.position[0], self.position[1], APPLE_SIZE, APPLE_SIZE))

# 初始化贪吃蛇和苹果
snake = Snake()
apple = Apple()

# 游戏主循环
running = True
clock = pygame.time.Clock()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP and snake.direction != (0, 1):
                snake.direction = (0, -1)
            elif event.key == pygame.K_DOWN and snake.direction != (0, -1):
                snake.direction = (0, 1)
            elif event.key == pygame.K_LEFT and snake.direction != (1, 0):
                snake.direction = (-1, 0)
            elif event.key == pygame.K_RIGHT and snake.direction != (-1, 0):
                snake.direction = (1, 0)

    snake.move()
    if snake.get_head_position() == apple.position:
        snake.length += 1
        apple.randomize_position()

    window.fill(BLACK)
    snake.draw(window)
    apple.draw(window)
    pygame.display.update()
    clock.tick(SNAKE_SPEED)

# 退出游戏
pygame.quit()

运行这段代码，将会弹出一个窗口，您可以使用上下左右箭头控制贪吃蛇的移动，目标是吃掉苹果，每吃一个苹果贪吃蛇的长度会增加
