副本可以理解为原对象变化不对副本产生影响(当然有深浅copy之分,这里不赘述了),视图就像是SQL数据库中的视图,原对象变化会导致视图对象发生变化,倘若数组想要得到副本可以使用实例方法copy来得到 //一维数组索引示例 (在python中切片与索引(花式索引除外)返回的是副本,但在numpy中只返回视图!!!需要用copy与deep copy...

This is not a valid argument IMO - it's up to me as a user (consenting adults and all...) what I do with my objects, including the indexes, and if I make a deep copy, it's a justified expectation (I would even argue: a built-in expectation of the word "deep") that this wi...
