这篇文章主要为大家详细介绍了python贪吃蛇游戏的编写代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

最近在学Python，想做点什么来练练手，命令行的贪吃蛇一般是C的练手项目，但是一时之间找不到别的，就先做个贪吃蛇来练练简单的语法。

由于Python监听键盘很麻烦，没有C语言的kbhit()，所以这条贪吃蛇不会自己动，运行效果如下：

要求：用#表示边框，用*表示食物，o表示蛇的身体，O表示蛇头，使用wsad来移动

Python版本：3.6.1

立即学习“Python免费学习笔记（深入）”；

系统环境：Win10

类：

　　board：棋盘，也就是游戏区域

　　snake：贪吃蛇，通过记录身体每个点来记录蛇的状态

　　game：游戏类

　　本来还想要个food类的，但是food只需要一个坐标，和一个新建，所以干脆使用list来保存坐标，新建food放在game里面，从逻辑上也没有太大问题

笔记：

　　1.Python 没有Switch case语句，可以利用dirt来实现

　　2.Python的=号是复制，复制引用，深复制需要使用copy的deepcopy()函数来实现

　　3.即使在成员函数内，也需要使用self来访问成员变量，这和C++、JAVA很不一样
