如何在Python中创建对象的副本？ [英] How can I create a copy of an object in Python?

问题描述

我想创建一个对象的副本。我想让新对象拥有旧对象的所有属性（字段的值）。但我想有独立的对象。因此，如果我改变新对象的字段的值，旧的对象不应该受到影响。

I would like to create a copy of an object. I want the new object to possess all properties of the old object (values of the fields). But I want to have independent objects. So, if I change values of the fields of the new object, the old object should not be affected by that.
