你好，我阅读了数据处理程序。我发现在Amazon数据集中，category_list是一个多重列表，如一个item可能有以下层次结构， [ ['Clothing, Shoes & Jewelry', 'Citizen’], ['Clothing, Shoes & Jewelry', 'Men', 'Watches', 'Wrist Watches’] ]。程序中采用X[-1][-1]来提取这个item的category，也就是例子中的多重层次列表中的最后一个列表的最后一项'Wrist Watches’。请问采取这样的策略处理数据，是基于什么考虑的？还是因为Amazon数据集category_list太杂揉了，采取这样的处理方式？ 我试图利用Amazon数据集来提取一个树型的目录结构，但是一直不成功。希望您回答上面的疑问？
