Si estás construyendo una aplicación o una API web, rara vez podrás poner todo en un solo archivo.

**FastAPI** proporciona una herramienta conveniente para estructurar tu aplicación manteniendo toda la flexibilidad.

/// info | Información

Si vienes de Flask, esto sería el equivalente a los Blueprints de Flask.

## Un ejemplo de estructura de archivos { #an-example-file-structure }

    //                                                                        ============

    /**
     * Gets a key match entity based on the form and current user info.
     *
     * @param form the create form
     * @param username the current username
     * @param currentTime the current time
     * @return optional key match entity
     */

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

/// info | 정보

FastAPI는 이를 위해 Pydantic 모델의 `.dict()`의 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank"> `exclude_unset` 매개변수</a>를 사용합니다.

/// info | 정보

아래 또한 사용할 수 있습니다:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

2) If a title is present, prefer these canonical titles (choose one canonical form where variants exist):

- `/// note | Примітка`
- `/// note | Технічні деталі`
- `/// tip | Порада`
- `/// warning | Попередження`
- `/// info | Інформація`
