EarthLiveSharp中cloudinary的CDN图片缓存自动清理python脚本

恰巧发现有个叫“earthlivesharp”，可用将日本向日葵8号卫星的地球实时图片设为屏保。向日葵8号卫星的地球实时图片官网为：，earthlivesharp的项目地址是：https://github.com/bitdust/earthlivesharp。
为了减轻向日葵8号的服务器负担，同时也是提高地球实时图片的获取成功率，需要使用cloudinary来做cdn。注册配置都在软件里有说明。

目前earthlivesharp暂时没有清理cloudinary的cdn图片缓存的功能，于是我用python写了一个，并尝试用gist管理，地址为：

同时，为了大家方便，顺便编译成了windows可执行文件，下载： https://pan.baidu.com/s/1c27fxeo 提取码：k33n
为了自己检索方便，顺便在这里附上python脚本源码，可以作为python如何使用restful接口的例子，相关工具类函数也便于参考。
