it is solution from chat gpt

woooow)

yes i did that ^^

You cam make a method static by the @staticmethod decorator.

Very Clear

Really great and easy solution! I'm really disappointed that I can't say that this is and clever and pest practice one time!

The reason a static method is a static method is because it doesn't require self or cls.

_ is often used as a variable that's unused (Other than in Lodash), it's just a variable name that doesn't really have a name.

Hiii...
What is the use of _ in (_,i)? Please explain.

It doesn't matter for this particular kata, but static methods don't have a self arg in the sense that other class methods have a self arg that refers to the instance of the class. What you'll actually get in self here is the first passed-in argument, which could be anything.
