最近开始学习python这门强大而有趣的语言，一开始是需要写爬虫从网上爬一些数据，后来才逐渐意识到python的强大之处。
个人认为python更像一门脚本语言，而我们熟悉的python程序也一般都是命令行运行，但如果开发的程序要面向普通用户，那图形界面就必不可少。
查询了相关资料，才发现python在这方面并不是强项，当然可以借助第三方模块构建图形界面，但如果对界面美观要求不是很高，可以采用python标准模块Tkinter(python2的叫法，python3已经改为小写tkinter)。
废话不多说，参照windows记事本的字体配置界面做了一个demo。
Python代码：

#!/usr/bin/env python
# coding: utf-8
