=== "Python 3.10+"

    ```Python hl_lines="7"
    {!> ../../../docs_src/query_params/tutorial002_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/query_params/tutorial002.py!}
    ```

Nesse caso, o parâmetro da função `q` será opcional, e `None` será o padrão.

!!! check "Verificar"

```Python hl_lines="9"
{!../../../docs_src/query_params/tutorial001.py!}
```

La partie appelée requête (ou **query**) dans une URL est l'ensemble des paires clés-valeurs placées après le `?` , séparées par des `&`.

Par exemple, dans l'URL :

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

			t.Errorf("errors happened when query first: %v", err)
		} else {
			CheckUser(t, first, users[0])
		}
	})

	t.Run("Last", func(t *testing.T) {
		var last User
		if err := DB.Where("name = ?", "find").Last(&last).Error; err != nil {
			t.Errorf("errors happened when query last: %v", err)
		} else {
			CheckUser(t, last, users[2])
		}
	})

	var all []User

```Python hl_lines="9"
{!../../../docs_src/query_params/tutorial002.py!}
```

この場合、関数パラメータ `q` はオプショナルとなり、デフォルトでは `None` になります。

!!! check "確認"
    パスパラメータ `item_id` はパスパラメータであり、`q` はそれとは違ってクエリパラメータであると判別できるほど**FastAPI** が賢いということにも注意してください。

## クエリパラメータの型変換

`bool` 型も宣言できます。これは以下の様に変換されます:

```Python hl_lines="9"
{!../../../docs_src/query_params/tutorial003.py!}
```

この場合、以下にアクセスすると:
