python小游戏据说这是一款还原度超高的小游戏，你感受下。

　　前言
　　哈喽，大家好呀~欢迎大家阅读小编的文章！
　　又到了每日游戏更新系列，看到这么如下.gif是不是让你想起来了童年吖~
　　贪吃蛇 的人气可谓是经久不衰，有过了许多不同的版本，但大体游戏规则都是控制蛇的向，
　　寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度
　　就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，还要注意其他的蛇！
　　哪个版本的贪吃蛇是你的童年
　　是这个
　　嘿嘿 ~~~
　　好了，放图片路
　　正文：
　　就是这个大工程今天带大家做一款 Python 版本的贪吃蛇 游戏！
