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 python

# 定义颜色变量
redColour = pygame.Color(255,0,0)

# 定义gameOver函数

 gameOverFont = pygame.font.Font('arial.ttf',72)
 gameOverSurf = gameOverFont.render('Game Over', True, greyColour)
 gameOverRect = gameOverSurf.get_rect()
 gameOverRect.mid = (320, 10)
 playSurface.blit(gameOverSurf, gameOverRect)
 pygame.display.flip()
 time.sleep(5)
 pygame.quit()
 sys.exit()

# 定义main函数

 # 初始化pygame
 pygame.init()
 fpsClock = pygame.time.Clock()
 # 创建pygame显示层

 raspberryPosition = [int(x20),int(y20)]
 raspberrySpaned = 1
 # 绘制pygame显示层
 playSurface.fill(blackColour)
 for position in snakeSegments:
 pygame.dra.rect(playSurface,hiteColour,Rect(position[0],position[1],20,20))
 pygame.dra.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)

 # 控制游戏速度
 fpsClock.tick(5)

if __name__ == "__main__":
 main()
