结果数据展示

上代码

import pandas as pd
tb_ts = pd.DataFrame(data={'单量': [2130,5102,3256,1297,1918,786,4331,
3603,5162,2591,2117,1568,6200,3651,5],
                        '重复量': [73,158,89,30,49,18,96,77,98,46,34,
23,94,44,0]})
tb_ts['重复率']=tb_ts['重复量']/tb_ts['单量']
tb_ts['重复率']=tb_ts['重复率'].apply(lambda x: format(x, '.2%'))
print(tb_ts)
