Tabs and `Info`/`Note`/`Warning`/etc. blocks should have the translation of their title added after a vertical bar (`|`).

**FastAPI** is all based on these type hints, they give it many advantages and benefits.

But even if you never use **FastAPI**, you would benefit from learning a bit about them.

/// note

If you are a Python expert, and you already know everything about type hints, skip to the next chapter.

## Motivation { #motivation }

Let's start with a simple example:

* **Machine Learning**: it normally requires lots of "matrix" and "vector" multiplications. Think of a huge spreadsheet with numbers and multiplying all of them together at the same time.

* 100% test coverage: cobertura de tests del 100%
* back and forth: de un lado a otro
* I/O (as in "input and output"): I/O (do not translate to "E/S")
* Machine Learning: Machine Learning (do not translate to "Aprendizaje Automático")
* Deep Learning: Deep Learning (do not translate to "Aprendizaje Profundo")
* callback hell: callback hell (do not translate to "infierno de callbacks")
* tip: Consejo (do not translate to "tip")

Las pestañas y los bloques `Info`/`Note`/`Warning`/etc. deben tener la traducción de su título añadida después de una barra vertical (`|`).

## Use Case { #use-case }

Let's start with an example **use case** and then see how to solve it with this.

Let's imagine that you have some **machine learning models** that you want to use to handle requests. 🤖

## Caso de Uso { #use-case }

Empecemos con un ejemplo de **caso de uso** y luego veamos cómo resolverlo con esto.

Imaginemos que tienes algunos **modelos de machine learning** que quieres usar para manejar requests. 🤖

  The jury all wrote down on their slates, `SHE doesn't believe
there's an atom of meaning in it,' but none of them attempted to
explain the paper.

  `If there's no meaning in it,' said the King, `that saves a
world of trouble, you know, as we needn't try to find any.  And
