最近发现了一个非常有意思的python小应用，觉得很赞，所以将学习记录一下。

下载之后大概就是这些文件了，出来的效果也很赞。

 

小图标制作的也很精致，更加觉得非常有意思了，接下来，看一下源码。

 源码

环境是windows+py3

所以，这里我们需要建立一个py2.7的虚拟环境，因为我安装了anaconda，所以可以采用conda建立一个虚拟环境

conda create -n python2.7 python=2.7

激活python2.7的虚拟环境

activate python2.7

退出虚拟环境

deactivate

删除虚拟环境

conda remove -n python2.7 --all

根据这个步骤，我就新建了一个名叫python2.7的虚拟环境。
