Python——贪吃蛇

以下是一个简单的贪吃蛇游戏的Python代码示例：

import pygame
import time
import random# 初始化 Pygame
pygame.init()# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)# 设置屏幕尺寸
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("贪吃蛇游戏")# 游戏帧率
clock = pygame.time.Clock()
snake_block_size = 20# 字体设置
font_style = pygame.font.SysFont(None, 50)
score_font = pygame.font.SysFont(None, 35)def your_score(score):value = score_font.render("Your Score: " + str(score), True, WHITE)screen.blit(value, [0, 0])def our_snake(snake_block_size, snake_list):for x in snake_list:pygame.draw.rect(screen, GREEN, [x[0], x[1], snake_block_size, snake_block_size])# 游戏主循环

这个代码使用Pygame库来创建一个简单的贪吃蛇游戏。在游戏中，玩家通过键盘控制贪吃蛇的移动方向，目标是吃到食物并尽可能多地增长长度。如果贪吃蛇碰到边界或自己的身体，游戏结束。游戏过程中会显示当前的分数。
