Python:乘法替代 [英] Python: multiplication override

问题描述

因此，我有一个自定义类，该类具有一个与int一起使用的__mul__函数.但是，在我的程序(在库中)中，它被反过来调用，即2 * x，其中x是我的类.有什么办法可以使用我的__mul__函数吗?

So, I've got a custom class that has a __mul__ function which works with ints. However, in my program (in libraries), it's getting called the other way around, i.e., 2 * x where x is of my class. Is there a way I can have it use my __mul__ function for this?

推荐答案

只需将以下内容添加到类定义中，您应该会很好:

Just add the following to the class definition and you should be good to go:

__rmul__ = __mul__
