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.我希望新对象拥有旧对象的所有属性(字段的值).但我想拥有独立的对象.所以，如果我改变新对象的字段值，旧对象应该不会受到影响.

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.

推荐答案

要获得完全独立的对象副本，您可以使用 copy.deepcopy() 函数.

To get a fully independent copy of an object you can use the copy.deepcopy() function.
