is the any function that converts to lowerCase and at the same time Capitalizes the first chars in the given strings? [closed]

Hello! all Engineers and programmers! There should be a function to make all characters in a given line of string or even list convert to lowerCase and at the same time Capitalize the first chars in the given strings. I found it very useful and have used my own functions in a variety of places such as search and delete, functions, where the user might write the wrong spelling name, mixed capitalized and lowercase.

Why there is not a built-in function that converts to lowerCase and at the same time Capitalizes the first chars in the given strings and removes punctuations?

I know how to solve it, However, I think there should be a generalized algorithm for this implication. Since we use it frequently, Don’t you agree?

If you know any, please share with us here! for future users!

Thanks!
