前言

我一直在用python 写一下有趣的东西，让编程不那么无聊，之前一直有写一个桌面宠物的想法，无奈这些都是依赖资源文件，没有图片资源没办法写里面的逻辑，直到我看见了 shimiji手机桌面宠物软件


这个软件提供了很多宠物的图片资源，这样就简单了，用 charles 对手机简单抓包，抓取到这些资源链接
http://pepeswap.com/mascot/78
另外示例图片链接
http://pepeswap.com/thumb/78
这里是78，其实号码从 3 到90 都是有资源的，就是没有1,2（1,2是软件内置的）
所以这里一共有 90-3+1=88个资源，这下子图片资源就解决了
然后编写代码

代码

先写一个管理这些资源的软件
