请用python写一个贪食蛇小游戏

下面是一个简单的 Python 贪吃蛇小游戏，它使用 Pygame 模块实现。

import pygame
import sys
import random

# Initialize game engine
pygame.init()

# Set up window
WIDTH = 800
HEIGHT = 600

# Colors
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)

# Snake block size
block_size = 10

# FPS
fps = pygame.time.Clock()

# Set up window
window = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("贪吃蛇")

# Game over function
def game_over():
    font = pygame.font.SysFont(None, 25)
    text = font.render("游戏结束，按 Q 退出游戏", True, RED)
    window.blit(text, [WIDTH/2-50, HEIGHT/2])
    pygame.display.update()
    while True:
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_q:
                    pygame.quit()
                    sys.exit()

# Game loop
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # Clear the screen
    window.fill(WHITE)

    # Draw the snake
    # ...

    # Draw the food
    # ...

    # Update screen
    pygame.display.update()

    # FPS
    fps.tick(10)

    # Check for collision with food
    # ...

    # Check for collision with walls or snake body
    # ...

    # Check if game over
    # ...

这是一个基础的游戏框架，您可以根据自己的需求扩展它。例如，您可以使用键盘事件处理玩家的控制，并在每帧中更新蛇的位置。

希望对您有所帮助！
