Es spielt keine Rolle. **FastAPI** weiß, was zu tun ist.

### Bagımlılıklar

Aynısı bağımlılıklar için de geçerlidir. Bir bağımlılık, "async def" yerine standart bir "def" işleviyse, harici iş parçacığı havuzunda çalıştırılır.

### Alt-bağımlıklar

<img src="/img/python-types/image05.png">

Sans types, c'est presque impossible à réaliser.

Vous remarquerez que la variable `item` n'est qu'un des éléments de la list `items`.

Et pourtant, l'éditeur sait qu'elle est de type `str` et pourra donc vous aider à l'utiliser.

#### `Tuple` et `Set`

C'est le même fonctionnement pour déclarer un `tuple` ou un `set` :

{*../../docs_src/python_types/tutorial007.py hl[1,4] *}

            KeyMap<Binding> keyMap = reader.getKeyMaps().get("main");
            keyMap.bind(new Reference("tailtip-toggle"), KeyMap.alt("s"));

            // start the shell and process input until the user quits with Ctrl-D
            AtomicReference<Exception> failure = new AtomicReference<>();
            while (true) {
                try {

### Bir `Enum` Sınıfı Oluşturalım

`Enum` sınıfını projemize dahil edip `str` ile `Enum` sınıflarını miras alan bir alt sınıf yaratalım.

`str` sınıfı miras alındığından dolayı, API dokümanı, değerlerin `string` tipinde olması gerektiğini anlayabilecek ve doğru bir şekilde işlenecektir.
