如何利用 Pandas 将不同店铺的销售业绩按业务员合并？

import pandas as pd# 示例数据data = pd.dataframe({    "业务员": ["张三", "李四", "张三", "王五", "李四", "张三"],    "店铺": ["a", "b", "c", "a", "d", "b"],    "业绩": [10, 20, 30, 5, 25, 15]})# 按业务员分组并求和result = data.groupby("业务员")["业绩"].sum()# 输出合并后的业绩print(result)

业务员李四    50王五     5张三    65
