以下是完整的 Python 贪吃蛇代码： ```python import pygame import time import random # 初始化pygame pygame.init() # 定义颜色 white = (255, 255, 255) yellow = (255, 255, 102) black = (0, 0, 0) red = (213, 50, 80) green = (0, 255, 0) blue = (50, 153, 213) # 定义游戏界面大小 dis_width = 800 dis_height = 600 # 创建游戏窗口 dis = pygame.display.set_mode((dis_width, dis_height)) pygame.display.set_caption('贪吃蛇游戏') # 定义游戏帧率 clock = pygame.time.Clock() # 定义蛇的大小 snake_block = 10 snake_speed = 15 # 定义字体样式 font_style = pygame.font.SysFont("bahnschrift", 25) score_font = pygame.font.SysFont("comicsansms", 35) def Your_score(score): value = score_font.render("你的得分: " + str(score), True, yellow) dis.blit(value, [0, 0]) def our_snake(snake_block, snake_list): for x in snake_list: pygame.draw.rect(dis, black, [x[0], x[1], snake_block, snake_block]) def message(msg, color): mesg = font_style.render(msg, True, color) dis.blit(mesg, [dis_width / 6, dis_height / 3]) def gameLoop(): game_over = False game_close = False # 蛇的初始位置 x1 = dis_width / 2 y1 = dis_height / 2 # 蛇每次移动的距离 x1_change = 0 y1_change = 0 # 蛇的身体列表 snake_List = [] Length_of_snake = 1 # 食物的随机位置 foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0 foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0 while not game_over: while game_close: dis.fill(blue) message("你输了！按 Q-退出 或 C-重新开始", red) Your_score(Length_of_snake - 1) pygame.display.update() for event in pygame.event.get(): if event.type == pygame.KEYDOWN: if event.key == pygame.K_q: game_over = True game_close = False if event.key == pygame.K_c: gameLoop() 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: x1_change = -snake_block y1_change = 0 elif event.key == pygame.K_RIGHT: x1_change = snake_block y1_change = 0 elif event.key == pygame.K_UP: y1_change = -snake_block x1_change = 0 elif event.key == pygame.K_DOWN: y1_change = snake_block x1_change = 0 # 判断蛇是否撞到边界 if x1 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0: game_close = True x1 += x1_change y1 += y1_change dis.fill(blue) pygame.draw.rect(dis, green, [foodx, foody, snake_block, snake_block]) snake_Head = [] snake_Head.append(x1) snake_Head.append(y1) snake_List.append(snake_Head) if len(snake_List) > Length_of_snake: del snake_List[0] # 判断蛇是否撞到自己 for x in snake_List[:-1]: if x == snake_Head: game_close = True our_snake(snake_block, snake_List) Your_score(Length_of_snake - 1) pygame.display.update() # 蛇吃到食物后身体增长 if x1 == foodx and y1 == foody: foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0 foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0 Length_of_snake += 1 clock.tick(snake_speed) pygame.quit() quit() # 启动游戏循环 gameLoop() ``` 这段代码创建了一个基本的贪吃蛇游戏，其中蛇可以在屏幕上移动，并且可以吃掉随机出现的食物。如果蛇撞到自己或者墙壁，游戏就会结束。游戏的得分会随着吃掉食物而增加。可以运行这段代码来体验游戏，或者根据需要对其进行修改和扩展[^2]。
