Em versões abaixo do Python 3.9, você importa `Annotated` de `typing_extensions`.

Ele já estará instalado com o **FastAPI**.

## `async` ve `await`

Python'un modern sürümleri, asenkron kodu tanımlamanın çok sezgisel bir yoluna sahiptir. Bu, normal "sequentıal" (sıralı) kod gibi görünmesini ve doğru anlarda sizin için "awaıt" ile bekleme yapmasını sağlar.

Sonuçları vermeden önce beklemeyi gerektirecek ve yeni Python özelliklerini destekleyen bir işlem olduğunda aşağıdaki gibi kodlayabilirsiniz:

```Python

* E altre funzionalità (grazie a Starlette) come:
    * **WebSockets**
    * **GraphQL**
    * test molto facili basati su `requests` e `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ...e altro ancora.

### Ejemplos de Estrategias para Pasos Previos

Esto **dependerá mucho** de la forma en que **implementarás tu sistema**, y probablemente estará conectado con la forma en que inicias programas, manejas reinicios, etc.

Aquí hay algunas ideas posibles:

* Un "Contenedor de Inicio" en Kubernetes que se ejecuta antes de tu contenedor de aplicación

   *
   * // is equivalent to
   *
   * static final Multimap<Character, String> FIRST_LETTER_MULTIMAP =
   *     new ImmutableListMultimap.Builder<Character, String>()
   *         .put('b', "anana")
   *         .putAll('a', "pple", "sparagus")
   *         .putAll('c', "arrot", "herry")
   *         .build();
   * }
   *
   * @since 33.2.0 (available since 21.0 in guava-jre)
   */
