You’re asking either for something very specific that happens to do what you’re looking for, or something so incredibly powerful and magical that it does pretty much anything.
The first option is unlikely, and you haven’t defined what it would be anyway.
The second option doesn’t belong in a programming language. That’s like replacing the English language with one word or a grunt to mean anything, in making it mean everything it loses meaning, there isn’t enough information in it.
But since python is a programming language, you could decide what that entails and then implement it.
That, in addition to ignoring case, would be something you can implement. It’s not going to be one operator, but it’s also not going to be a lot of code, or difficult.
