roc*_*555 5 python dataframe pandas
想象我有这样的数据框：
item name gender
banana tom male
banana kate female
apple kate female
kiwi jim male
apple tom male
banana kimmy female
kiwi kate female
banana tom male
有什么方法可以删除该人仅关联（购买）少于 2 个项目的行？我也不想删除重复项。所以我想要的输出是这样的：
item name gender
banana tom male
banana kate female
apple kate female
apple tom male
kiwi kate female
banana tom male
