游戏规则

使用↑ ↓ ← →四个键进行游玩，蛇头不能碰到自己

在结束时会有分数打在上面

补充说明

• pygame不属于Python自带库，需要自己在命令行安装，命令如下

pip install pygame

如果想把程序给朋友炫耀一下，但他又没有Python环境时可以这样：

1. 在命令行下载pyinstaller库（这个库是用来把.py文件转成.exe可执行文件的）

   pip install pyinstaller

2.   用此命令把.py文件转成.exe可执行文件(路径不能包含空格)

   pyinstaller -F 路径

   备注：-F是用来转成一个文件的，如果不加的话默认转成一个目录
3. 最后在这一行找到转出文件的路径
