首先爬取who官网疫情数据，由于动图制作数据太多报错，因此截取其排名前15国家。

效果如下：

由于文件太大，csdn只支持5兆上传，因此压缩后模糊了

完整代码如下：

import pandas as pd
import matplotlib
import matplotlib.pyplot as plt
import  matplotlib.ticker as ticker
import matplotlib.animation as animation

matplotlib.rcParams['animation.embed_limit'] = 2**128

     '#aafbff', '#f7bb5f']

animator.save("动态排序.gif")

爬取的数据，其excel数据格式如下：
