Bu tür tip belirteçlerini desteklemek için özel olarak mevcuttur.

#### `List`

Örneğin `str` değerlerden oluşan bir `list` tanımlayalım.

From `typing`, import `List` (büyük harf olan `L` ile):

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial006.py!}
```

Değişkenin tipini yine iki nokta üstüste (`:`) ile belirleyin.

tip olarak `List` kullanın.

Lo importante es que usando los tipos de Python estándar en un único lugar (en vez de añadir más clases, decorator, etc.) **FastAPI** hará mucho del trabajo por ti.

```
http://127.0.0.1:8000/items/foo?short=on
```

veya

```
http://127.0.0.1:8000/items/foo?short=yes
```

veya adres, herhangi farklı bir harf varyasyonu içermesi durumuna rağmen (büyük harf, sadece baş harfi büyük kelime, vb.) fonksiyonunuz, `bool` tipli `short` parametresini `True` olarak algılayacaktır. Aksi halde `False` olarak algılanacaktır.

Si simplemente no lo sabes, usa `def` normal.

---

**Nota**: puedes mezclar `def` y `async def` en tus *path operation functions* tanto como lo necesites y definir cada una utilizando la mejor opción para ti. FastAPI hará lo correcto con ellos.

De todos modos, en cualquiera de los casos anteriores, FastAPI seguirá funcionando de forma asíncrona y será extremadamente rápido.

**available machines** taking into account the amount of memory needed by them, and the amount available in the machines in the cluster.

If your application is **simple**, this will probably **not be a problem**, and you might not need to specify hard memory limits. But if you are **using a lot of memory** (for example with **machine learning** models), you should check how much memory you are consuming and adjust the **number of containers** that runs in **each machine** (and maybe add more machines...

* `fixedquery`: has the exact value `fixedquery`.
* `$`: ends there, doesn't have any more characters after `fixedquery`.

If you feel lost with all these **"regular expression"** ideas, don't worry. They are a hard topic for many people. You can still do a lot of stuff without needing regular expressions yet.

But whenever you need them and go and learn them, know that you can already use them directly in **FastAPI**.

!!! tip "Consejo"
    `JSONResponse` en sí misma es una subclase de `Response`.

Y cuando devuelves una `Response`, **FastAPI** la pasará directamente.

No hará ninguna conversión de datos con modelos Pydantic, no convertirá el contenido a ningún tipo, etc.

Esto te da mucha flexibilidad. Puedes devolver cualquier tipo de dato, sobrescribir cualquier declaración de datos o validación, etc.
