```Python
q: Annotated[str, Query()] = "rick"
```

... ou dans des bases de code plus anciennes, vous trouverez :

```Python
q: str = Query(default="rick")
```

### Avantages de `Annotated` { #advantages-of-annotated }

**L’utilisation de `Annotated` est recommandée** plutôt que la valeur par défaut dans les paramètres de fonction, c’est **mieux** pour plusieurs raisons. 🤓

```Python
q: Annotated[str, Query()] = "rick"
```

...або у старих кодових базах ви знайдете:

```Python
q: str = Query(default="rick")
```

### Переваги використання `Annotated` { #advantages-of-annotated }

Використання `Annotated` є рекомендованим замість задання значення за замовчуванням у параметрах функції, оскільки воно краще з кількох причин. 🤓

因此，你可以（且更推薦）這樣寫：

```Python
q: Annotated[str, Query()] = "rick"
```

…或在較舊的程式碼中你會看到：

```Python
q: str = Query(default="rick")
```

### `Annotated` 的優點 { #advantages-of-annotated }

建議使用 `Annotated`，而不是在函式參數上使用（舊式的）預設值寫法，理由很多，且更好。🤓

函式參數的「預設值」就是「實際的預設值」，這在 Python 的直覺上更一致。😌

你也可以在沒有 FastAPI 的其他地方「直接呼叫」同一個函式，而且能「如預期」運作。若有「必填」參數（沒有預設值），你的「編輯器」會提示錯誤，「Python」在執行時也會抱怨你未傳遞必填參數。

```Python
q: Annotated[str, Query()] = "rick"
```

...veya eski kod tabanlarında şuna rastlarsınız:

```Python
q: str = Query(default="rick")
```

### `Annotated`’ın avantajları { #advantages-of-annotated }

Fonksiyon parametrelerindeki varsayılan değer stiline göre **`Annotated` kullanmanız önerilir**; birden fazla nedenle **daha iyidir**. 🤓

```Python
q: Annotated[str, Query()] = "rick"
```

...o en code bases más antiguas encontrarás:

```Python
q: str = Query(default="rick")
```

### Ventajas de `Annotated` { #advantages-of-annotated }

Usar `Annotated` es recomendado en lugar del valor por defecto en los parámetros de función, es mejor por múltiples razones. 🤓
