本文实例为大家分享了python贪吃蛇游戏的具体代码，供大家参考，具体内容如下

贪吃蛇游戏截图：

首先安装pygame，可以使用pip安装pygame：

pip install pygame

运行以下代码即可：

#!/usr/bin/env pythonimport pygame,sys,time,randomfrom pygame.locals import *# 定义颜色变量redColour = pygame.Color(255,0,0)blackColour = pygame.Color(0,0,0)whiteColour = pygame.Color(255,255,255)greyColour = pygame.Color(150,150,150)# 定义gameOver函数def gameOver(playSurface): gameOverFont = pygame.font.Font('arial.ttf',72) gameOverSurf = gameOverFont.render('Game Over', True, greyColour) gameOverRect = gameOverSurf.get_rect() gameOverRect.midtop = (320, 10) playSurface.blit(gameOverSurf, gameOverRect) pygame.display.flip() time.sleep(5) pygame.quit() sys.exit()# 定义main函数def main(): # 初始化pygame pygame.init() fpsClock = pygame.time.Clock() # 创建pygame显示层 playSurface = pygame.display.set_mode((640,480)) pygame.display.set_caption('Raspberry Snake') # 初始化变量 snakePosition = [100,100] snakeSegments = [[100,100],[80,100],[60,100]] raspberryPosition = [300,300] raspberrySpawned = 1 direction = 'right' changeDirection = direction while True: # 检测例如按键等pygame事件 for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() elif event.type == KEYDOWN: # 判断键盘事件 if event.key == K_RIGHT or event.key == ord('d'): changeDirection = 'right' if event.key == K_LEFT or event.key == ord('a'): changeDirection = 'left' if event.key == K_UP or event.key == ord('w'): changeDirection = 'up' if event.key == K_DOWN or event.key == ord('s'): changeDirection = 'down' if event.key == K_ESCAPE: pygame.event.post(pygame.event.Event(QUIT)) # 判断是否输入了反方向 if changeDirection == 'right' and not direction == 'left': direction = changeDirection if changeDirection == 'left' and not direction == 'right': direction = changeDirection if changeDirection == 'up' and not direction == 'down': direction = changeDirection if changeDirection == 'down' and not direction == 'up': direction = changeDirection # 根据方向移动蛇头的坐标 if direction == 'right': snakePosition[0] += 20 if direction == 'left': snakePosition[0] -= 20 if direction == 'up': snakePosition[1] -= 20 if direction == 'down': snakePosition[1] += 20 # 增加蛇的长度 snakeSegments.insert(0,list(snakePosition)) # 判断是否吃掉了树莓 if snakePosition[0] == raspberryPosition[0] and snakePosition[1] == raspberryPosition[1]: raspberrySpawned = 0 else: snakeSegments.pop() # 如果吃掉树莓，则重新生成树莓 if raspberrySpawned == 0: x = random.randrange(1,32) y = random.randrange(1,24) raspberryPosition = [int(x*20),int(y*20)] raspberrySpawned = 1 # 绘制pygame显示层 playSurface.fill(blackColour) for position in snakeSegments: pygame.draw.rect(playSurface,whiteColour,Rect(position[0],position[1],20,20)) pygame.draw.rect(playSurface,redColour,Rect(raspberryPosition[0], raspberryPosition[1],20,20)) # 刷新pygame显示层 pygame.display.flip() # 判断是否死亡 if snakePosition[0] > 620 or snakePosition[0] < 0: gameOver(playSurface) if snakePosition[1] > 460 or snakePosition[1] < 0: for snakeBody in snakeSegments[1:]: if snakePosition[0] == snakeBody[0] and snakePosition[1] == snakeBody[1]: gameOver(playSurface) # 控制游戏速度 fpsClock.tick(5)if __name__ == "__main__": main()

操作方法：

上下左右键或wsad键控制

ESC键退出游戏
