Vamos a hacer que, aunque `q` sea opcional, siempre que se proporcione, su longitud no exceda los 50 caracteres.

### Importar `Query` y `Annotated` { #import-query-and-annotated }

Para lograr eso, primero importa:

* `Query` desde `fastapi`
* `Annotated` desde `typing`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

construir una API de Python para producción, altamente recomendaría **FastAPI**. Está **hermosamente diseñado**, es **simple de usar** y **altamente escalable**, se ha convertido en un **componente clave** en nuestra estrategia de desarrollo API primero y está impulsando muchas automatizaciones y servicios como nuestro Ingeniero Virtual TAC._"

**FastAPI** no existiría si no fuera por el trabajo previo de otros.

Se han creado muchas herramientas antes que han ayudado a inspirar su creación.

He estado evitando la creación de un nuevo framework durante varios años. Primero intenté resolver todas las funcionalidades cubiertas por **FastAPI** usando muchos frameworks diferentes, plug-ins y herramientas.
