方法/步骤
1、python机器学习实践指南，原书蜣贺鱿柢代码：df.groupby('class')['petalwidth']\.agg({'de造婷用痃lta':lambdax:x.max()-x.min(),'max':np.max,'min':np.min})
2、运酚祯馄嫱行后报错：FutureWarning:usingadictonaSeriesforaggregationisdeprecatedandwillberemove颊俄岿髭dinafutureversion'max':np.max,'min':np.min})
3、修改如下：defdelta(group):returnmax(group)-min(group)df.groupby('class')['petalwidth'].agg([delta])
4、运行结果：如下图
