Python小Demo：Tkinter制作足迹地图

环境

需要Tkinter与百度开源的pyecharts
安装方法：
pyecharts安装

pip install pyecharts

# 地图bao
pip install echarts-countries-pypkg
pip install echarts-china-provinces-pypkg
pip install echarts-china-cities-pypkg
pip install echarts-china-counties-pypkg
pip install echarts-china-misc-pypkg

功能

1. 制作具有下拉列表的界面展示中国城市列表，共343座城市
2. 点击OK按钮生成足迹地图，自动打开浏览器查看足迹地图
3. 每8个城市换行
