No, this is literally the dumbest way possible to accomplish the task. It is as close to a brute force approach as you can get, I can see no way in which it could be less efficient without being malicious. And it is the only way of accomplishing this task in the standard library of a language which prides itself on performance and maintainability.

Also, thanks for the ad hominem, perhaps you shouldn’t attach your self worth to a programming language and see how that works out for you.
