<summary>Acerca del comando <code>fastapi dev</code>...</summary>

El comando `fastapi dev` lee tu archivo `main.py` automáticamente, detecta la app **FastAPI** en él y arranca un servidor usando [Uvicorn](https://www.uvicorn.dev).

Por defecto, `fastapi dev` comenzará con auto-recarga habilitada para el desarrollo local.

Puedes leer más sobre esto en la [documentación del CLI de FastAPI](https://fastapi.tiangolo.com/es/fastapi-cli/).

Vemos que vamos a necesitar algunas dependencias usadas en varios lugares de la aplicación.

Así que las ponemos en su propio módulo `dependencies` (`app/dependencies.py`).

Ahora utilizaremos una dependencia simple para leer un header `X-Token` personalizado:

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Consejo

    * Como o parâmetro `q` é declarado com `= None`, ele é opcional.
    * Sem o `None` ele seria obrigatório (como o corpo no caso de `PUT`).
* Para requisições `PUT` para `/items/{item_id}`, lerá o corpo como JSON:
    * Verifica que tem um atributo obrigatório `name` que deve ser `str`.
    * Verifica que tem um atributo obrigatório `price` que tem que ser um `float`.

### Özet { #recap }

Özetle, parametrelerin, body'nin vb. type'larını fonksiyon parametreleri olarak **bir kere** tanımlarsınız.

Bunu standart modern Python tipleriyle yaparsınız.

Yeni bir syntax, belirli bir kütüphanenin method'larını ya da class'larını vb. öğrenmeniz gerekmez.

Sadece standart **Python**.

    assertThat(matcher.negate().negate().toString()).isEqualTo(expectedNormal);

    // The precomputed form is different on regular platforms but the same on j2cl and j2kt.
    // Hence isAnyOf here.
    assertThat(matcher.precomputed().toString()).isAnyOf(expectedNormal, expectedPrecomputed);
    assertThat(matcher.negate().precomputed().negate().toString())
        .isAnyOf(expectedNormal, expectedPrecomputed);
