python写贪吃蛇游戏

好的，以下是一个简单的 Python 贪吃蛇游戏的代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置窗口大小和标题
window_width = 500
window_height = 500
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("贪吃蛇游戏")

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 定义蛇和食物的大小
block_size = 10

# 定义字体
font = pygame.font.SysFont(None, 25)

# 定义函数，用于显示文字
def message_to_screen(msg, color):
    screen_text = font.render(msg, True, color)
    window.blit(screen_text, [window_width/2, window_height/2])

# 定义主函数
def gameLoop():
    # 定义游戏结束变量
    game_over = False

    # 定义蛇的初始位置和长度
    lead_x = window_width/2
    lead_y = window_height/2
    lead_x_change = 0
    lead_y_change = 0
    snake_List = []
    Length_of_snake = 1

    # 定义食物的初始位置
    food_x = round(random.randrange(0, window_width-block_size)/10.0)*10.0
    food_y = round(random.randrange(0, window_height-block_size)/10.0)*10.0

    # 游戏循环
    while not game_over:
        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    lead_x_change = -block_size
                    lead_y_change = 0
                elif event.key == pygame.K_RIGHT:
                    lead_x_change = block_size
                    lead_y_change = 0
                elif event.key == pygame.K_UP:
                    lead_y_change = -block_size
                    lead_x_change = 0
                elif event.key == pygame.K_DOWN:
                    lead_y_change = block_size
                    lead_x_change = 0

        # 判断蛇是否撞到边界
        if lead_x >= window_width or lead_x < 0 or lead_y >= window_height or lead_y < 0:
            game_over = True

        # 移动蛇的位置
        lead_x += lead_x_change
        lead_y += lead_y_change

        # 绘制背景和食物
        window.fill(white)
        pygame.draw.rect(window, red, [food_x, food_y, block_size, block_size])

        # 绘制蛇
        snake_Head = []
        snake_Head.append(lead_x)
        snake_Head.append(lead_y)
        snake_List.append(snake_Head)

        if len(snake_List) > Length_of_snake:
            del snake_List[0]

        for segment in snake_List[:-1]:
            if segment == snake_Head:
                game_over = True

        for segment in snake_List:
            pygame.draw.rect(window, black, [segment[0], segment[1], block_size, block_size])

        pygame.display.update()

        # 判断是否吃到了食物
        if lead_x == food_x and lead_y == food_y:
            food_x = round(random.randrange(0, window_width-block_size)/10.0)*10.0
            food_y = round(random.randrange(0, window_height-block_size)/10.0)*10.0
            Length_of_snake += 1

        # 设置游戏帧率
        clock = pygame.time.Clock()
        clock.tick(15)

    # 退出 Pygame
    pygame.quit()
    quit()

# 运行游戏
gameLoop()

这个程序使用 Pygame 模块实现了一个简单的贪吃蛇游戏。玩家通过控制方向键移动蛇，吃掉食物来增加蛇的长度，直到蛇撞到边界或者自己的身体时游戏结束。
