python:类覆盖“is"行为 [英] python: class override "is" behavior

问题描述

我正在编写一个封装任意对象的类，包括简单类型.我想让is"关键字对封装的值进行操作，比如这个行为:

I'm writing a class which encapsulates any arbitrary object, including simple types. I want the "is" keyword to operate on the encapsulated value, such as this behavior:

Wrapper(True) is True -> True
Wrapper(False) is True -> False
Wrapper(None) is None -> True
Wrapper(1) is 1 -> True

有没有我可以重写的对象方法来获得这种行为?

Is there any object method I can override to get this behavior?

推荐答案

没有.is、and 和 or 不能重载.

No. is, and, and or cannot be overloaded.
