Unlike Python s array, which implements __copy__ and __deepcopy__ so that the copy module can use it,
Python s list does not implement __copy__ and __deepcopy__. (although there is a copy method)
Instead, the logic related to list copy is implemented in the copy function and deepcopy function of the copy module.
为什么有<代码>copy__和_deepcopy__ 方法不同?
如list ,copy.deepcopy(),了解如何构造一个深的副本,从而list。 不需要自己的<代码>_deepcopy__()。
添加一种方法,例如,如果甲型六氯环己烷需要做比它所继承的(例如<条码>目标或<条码>>(例如<<>>>>>)所定义的更为多的事情的话。
请注意,这意味着您不应使用某一类别是否实施_deepcopy__的信息。 是否作为解决问题的代理答案,这一类别是否深入探讨?
