想请问一下 要怎么样设置 1随着时间加速 2弹出game over并按任意键重置（用print和input都是在py有 游戏里不弹出） 3苹果位置和蛇不重叠 4方向键也可以控制上下左右
另外想请问下 randint和randrange的区别
以下是我的贪吃蛇小游戏代码
谢谢大佬们

randint左右闭区间，randrange左闭右开。建议用pygame，可以参考下我写的。我的这个是猝死型的，你可以写个检测果子和蛇不能重叠，重叠的话重新生成果子就行。加速的话，加个变量记录下时间，到达时间更改移动速度就行。game over的话自己做个结束页面的图片，死亡后加载，然后程序检测是否有按键按下，按下的话重新开始
