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

没有问题

发现一个bug，有时候会不显示食物，修改代码测试之后发现有时候食物会随机出现在上一次蛇头传送过的墙边，并且这种食物不能通过边界传送吃到，身体越长越容易出现这个bug。
（虽然已经在随机产生食物之前排除了蛇身所在的位置）
可以把 move(self) 方法内的 # 墙面传送区块剪切到 # 位置移动区块后边解决。
