When a method is called on an object in python as:
在python中的对象上调用方法时:
obj.func()
then python passes the obj as the first argument to the func(). I want to do something like:
然后python将obj作为第一个参数传递给func()。我想做的事情如下:
[obj1, obj2].func()
and have it processed as:
并将其处理为:
[obj1.func(), obj.func()]
Is there a way of defining this kind of methods in python?
有没有办法在python中定义这种方法?

The only way to do exactly what you're asking for is to subclass python build-in class list.
完全按照你的要求做的唯一方法是继承python内置类列表。
This should help.

PS: it is a really bad thing to do that though.

If you use a list comprehension, you get basically what you need:
如果你使用列表理解,你基本上得到你需要的:
[obj.func() for obj in [obj1, obj2]]
This is standard syntax and is easy to understand for other Python programmers.
这是标准语法,对于其他Python程序员来说很容易理解。
