Nice solution

I guess i do. Maybe after I¨ll actually programm something real it might get better.. Still thank you and have nice day. :)

The description doesn't say it.

What will happen if someone has a two part name, like von Braun? Or it will include some tags, processed afterwards, that should be not capitalized?

You're overthinging it :)

I guess. Still better behaviour would be to capitalize every words inside the answer, don't you thing?

How exactly it matters? say_hello('john') => "Hello, john" would be an expected behavior.

Maybe I missed it but what about the case when name elements can be lowercase?

Love me some f-strings

In my opinion the min and max functions are overkill. But interesting solution.
