# Archivos de Request

Puedes definir archivos que serán subidos por el cliente utilizando `File`.

/// info | Información

Para recibir archivos subidos, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo y luego instalarlo, por ejemplo:

```console

     * @param parentUrl the parent URL that referenced this child URL
     * @param weight the weight/priority of the child URL

Puedes retornar un `dict`, `list`, valores singulares como `str`, `int`, etc.

También puedes retornar modelos de Pydantic (verás más sobre eso más adelante).

Hay muchos otros objetos y modelos que serán automáticamente convertidos a JSON (incluyendo ORMs, etc). Intenta usar tus favoritos, es altamente probable que ya sean compatibles.

## Recapitulación

* Importa `FastAPI`.
* Crea una instancia `app`.

* The **file** that can be **executed** by the operating system, for example: `python`, `python.exe` or `uvicorn`.
* A particular program while it is **running** on the operating system, using the CPU, and storing things in memory. This is also called a **process**.

### What is a Process { #what-is-a-process }

Y si ese `Response` tiene un media type JSON (`application/json`), como es el caso con `JSONResponse` y `UJSONResponse`, los datos que devuelvas se convertirán automáticamente (y serán filtrados) con cualquier `response_model` de Pydantic que hayas declarado en el *path operation decorator*.
