The epidemic situation is unbearable for both individuals and enterprises. I hope that the epidemic will pass as soon as possible, which is a small wish of ordinary people.

Relatives and friends around us are more or less affected by the epidemic. Let's find out Wuhan friends in the circle of friends through python to give them care.

The first step is to install wxpy first, and then the pyecharts module used in map drawing in this article

pip install wxpy # Support wechat related functions

pip install pyecharts # Support map drawing function

pip install pyecharts_snapshot

Step 2: download the required map data package as required. After pyecharts v0.3.2, pyecharts will no longer bring its own map js file. If you need to use the map chart, you can install the corresponding map file package. Here we choose the provincial map of China: echarts-china-provinces-pypkg to download and display the map of Hubei province

Global country map: ecrats countries pypkg: world map and 213 countries, including China

Provincial map of China: echarts China provinces pypkg: 23 provinces, 5 autonomous regions

City map of China: eckarts China cities pypkg: 370 Chinese cities

County level map of China: echarts China counts pypkg: 2882 counties and districts in China

China regional map: echarts China misc pypkg: 11 regional maps of China, such as South China and North China.

In addition, the UK 2016 constituency map: echarts United Kingdom pypkg: the UK constituency map can be used to draw data related to political economy

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

When the environment is ready, the design strategy follows.

1. Get the friend information through Bot(cache_path=True).friends() function to find the Hubei friend we are looking for;

2. Add custom geojson data to eCharts to realize map display;

3. Custom blessing script, randomly sent to Hubei friends list;
