刚开始学python，选了这个题目，把代码放上来留念，没有用到很流行的框架，所以代码量挺大  
GUI用wxpython写的

数据分析部分：用matplotlib制图，只是粗浅学了一些，所以画的不够精美，数据过少，分析的可能有点问题，emmm，一共画了四张图， “2017-2018微博转发/点赞量折线统计图”、 ‘原创微博与转发微博统计图’ 、 ‘微博发布工具统计图’、 ‘微博使用心情统计图’

\#只选择2017-2018年两年的数据，因为微博数太多，横轴日期占比太大，matplotlib的横坐标显示不完全，中间会有大量重叠，这里数据分析的算法并不好，结果出来还是会有很大重叠，如果有更好的办法请大佬指教

本篇只适合新手简单学习，笔者也刚学，加上复习周，后期会逐渐完善，毕竟UI写的太丑了 ！  
另：关于获取本地用户cookie和微博账号的id操作比较简单在此不再做详细解释。如果程序跑不出来相信我一定是cookie问题
