* Lấy một `first_name` và `last_name`.
* Chuyển đổi kí tự đầu tiên của mỗi biến sang kiểu chữ hoa với `title()`.
* <abbr title="Đặt chúng lại với nhau thành một. Với các nội dung lần lượt.">Nối</abbr> chúng lại với nhau bằng một kí tự trắng ở giữa.

It doesn't use a data validation, serialization and documentation third-party library like Pydantic, it has its own. So, these data type definitions would not be reusable as easily.

It requires a little bit more verbose configurations. And as it is based on WSGI (instead of ASGI), it is not designed to take advantage of the high performance provided by tools like Uvicorn, Starlette and Sanic.
