【Python】Pygame模块实现功能超赞的贪吃蛇

一周前 放假无聊 做了一个贪吃蛇 并发布了1.2版本，现在 2.0最终版已开发完成！效果如图：
不知为何图片会跑到末尾去啊啊啊啊啊，编辑也不显示 无奈啊

目前实现的功能有：·贪吃蛇基本游戏功能，·可选有无墙，·生成大食物 ·速度变化(有上限) ·得分减少
·地图选择功能　·自定义速度功能 　·记录最高分功能　·玩家绘制地图功能
百度网盘：exe版本，无需python解释器https://pan.baidu.com/s/1hcPafSZyu_n_6F5eUti4Wg 可直接执行，提取码：yrqk
从1.0版本修改到2.0版本，代码也从100多行到现在的700多行，在这个过程中也总结了一些经验心得，入门编程的可以看下，大佬。。大佬可以出门左转{:1_911:}

• 按照语法规范写代码。 虽然此代码按照PEP8规范书写，但写多了看着还是眼花缭乱（ 代码起高了， 听起来不顺眼 ）。
• 分好模块。 方便添加功能，修改代码。 在楼主逐渐添加功能的过程中，并不是把新功能放在一个新的函数或者类里面就OK的，还要对之前的代码进行大量修改，做好模块分类，可以精准定位。虽然楼主在制作1.0版本时就构建了框架，考虑了可能的模块，11分好，（一开始分了两个文件来完成，由于贪图一时方便在1.2版本就合并为一个文件。若非这样，楼主的代码会更易读），但越往后完善功能 感觉对于模块的分类越模糊，终于在即将完成2.0版本时有了新的分类想法，奈何已经完成了700多行代码， 无力重写，不过一定会对以后在开发大量代码有所帮助。感觉模块分类这东西都是据经验而评吧，楼主也是第一次开发这么多代码的文件，包括核心算法在内没有参考任何东西（初心就是练一下手）。
• 做好注释。 注释不必详细，但要能够让你自己知道这个东西是干嘛用的。在这个代码从100多行到700多行来，只有每天晚上有几个小时来敲代码，白天经历那么多事，不会对于之前定义的变量和方法都历历在目，只能记得有这个东西，这时候就要回去阅读自己的代码，有些方法没加注释，就要一步一步的看，看它各种传递各种调用。。
• 添加新功能时在新文件中完成。 由于添加新功能的同时会对已完成的代码进行修改，若在原来的文件上直接进行，（如果突然有了更简单的算法 或者目前正在实现的算法比较难实现 ）须重写时，特别时无法撤回时，会很麻烦。 好在楼主在1.0版本的基础上添加功能时遇到了这样的问题，才有了1.x 2.x 版本的诞生:lol
