Python 贪吃蛇游戏：代码示例和玩法

以下是使用Python编写的简单贪吃蛇游戏的示例代码：\n\npython\nimport pygame\nimport time\nimport random\n \npygame.init()\n \nwhite = (255, 255, 255)\nyellow = (255, 255, 102)\nblack = (0, 0, 0)\nred = (213, 50, 80)\ngreen = (0, 255, 0)\nblue = (50, 153, 213)\n \ndis_width = 800\ndis_height = 600\n \ndis = pygame.display.set_mode((dis_width, dis_height))\npygame.display.set_caption('Snake Game')\n \nclock = pygame.time.Clock()\nsnake_block = 10\nsnake_speed = 30\n \nfont_style = pygame.font.SysFont(None, 50)\nscore_font = pygame.font.SysFont(None, 35)\n \n \ndef our_snake(snake_block, snake_list):\n for x in snake_list:\n pygame.draw.rect(dis, black, [x[0], x[1], snake_block, snake_block])\n \n \ndef message(msg, color):\n mesg = font_style.render(msg, True, color)\n dis.blit(mesg, [dis_width / 6, dis_height / 3])\n \n \ndef gameLoop():\n game_over = False\n game_close = False\n \n x1 = dis_width / 2\n y1 = dis_height / 2\n \n x1_change = 0\n y1_change = 0\n \n snake_List = []\n Length_of_snake = 1\n \n foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0\n foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0\n \n while not game_over:\n \n while game_close == True:\n dis.fill(blue)\n message("You Lost! Press Q-Quit or C-Play Again", red)\n pygame.display.update()\n \n for event in pygame.event.get():\n if event.type == pygame.KEYDOWN:\n if event.key == pygame.K_q:\n game_over = True\n game_close = False\n if event.key == pygame.K_c:\n gameLoop()\n \n for event in pygame.event.get():\n if event.type == pygame.QUIT:\n game_over = True\n if event.type == pygame.KEYDOWN:\n if event.key == pygame.K_LEFT:\n x1_change = -snake_block\n y1_change = 0\n elif event.key == pygame.K_RIGHT:\n x1_change = snake_block\n y1_change = 0\n elif event.key == pygame.K_UP:\n y1_change = -snake_block\n x1_change = 0\n elif event.key == pygame.K_DOWN:\n y1_change = snake_block\n x1_change = 0\n \n if x1 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0:\n game_close = True\n x1 += x1_change\n y1 += y1_change\n dis.fill(blue)\n pygame.draw.rect(dis, green, [foodx, foody, snake_block, snake_block])\n snake_Head = []\n snake_Head.append(x1)\n snake_Head.append(y1)\n snake_List.append(snake_Head)\n if len(snake_List) > Length_of_snake:\n del snake_List[0]\n \n for x in snake_List[:-1]:\n if x == snake_Head:\n game_close = True\n \n our_snake(snake_block, snake_List)\n pygame.display.update()\n \n if x1 == foodx and y1 == foody:\n foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0\n foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0\n Length_of_snake += 1\n \n clock.tick(snake_speed)\n \n pygame.quit()\n quit()\n \n \ngameLoop()\n\n\n运行此代码将打开一个窗口，玩家可以通过键盘上的箭头控制贪吃蛇的移动，目标是吃掉食物并避免撞到墙壁或自身。游戏结束后，玩家可以选择重新开始或退出。
