!!! note
    **FastAPI** saura que la valeur de `q` n'est pas requise grâce à la valeur par défaut `= None`.

---

Si vous ne savez pas, utilisez seulement `def` comme vous le feriez habituellement.

---

**Note** : vous pouvez mélanger `def` et `async def` dans vos *fonctions de chemin* autant que nécessaire, **FastAPI** saura faire ce qu'il faut avec.

Au final, peu importe le cas parmi ceux ci-dessus, **FastAPI** fonctionnera de manière asynchrone et sera extrêmement rapide.

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

!!! info
    `**second_user_data` nghĩa là:

    Truyền các khóa và giá trị của dict `second_user_data` trực tiếp như các tham số kiểu key-value, tương đương với: `User(id=4, name="Mary", joined="2018-11-30")`

### Được hỗ trợ từ các trình soạn thảo

Si vous l'exécutez avec :

<div class="termy">

```console
$ python myapp.py
```

</div>

alors la variable interne `__name__` de votre fichier, créée automatiquement par Python, aura pour valeur la chaîne de caractères `"__main__"`.

Ainsi, la section :

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

va s'exécuter.

    name: str
    joined: date
```

Das kann nun wie folgt verwendet werden:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

!!! info
    `**second_user_data` bedeutet:

my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

!!! info "情報"
    `**second_user_data` は以下を意味します：

    `second_user_data`辞書のキーと値を直接、キーと値の引数として渡します。これは、`User(id=4, name="Mary", joined="2018-11-30")`と同等です。

  And so she went on, taking first one side and then the other,
and making quite a conversation of it altogether; but after a few
minutes she heard a voice outside, and stopped to listen.

  `Mary Ann!  Mary Ann!' said the voice.  `Fetch me my gloves
this moment!'  Then came a little pattering of feet on the
stairs.  Alice knew it was the Rabbit coming to look for her, and
