## 경로 임포트

먼저 `fastapi`에서 `Path`를 임포트합니다:

```Python hl_lines="3"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

## 메타데이터 선언

`Query`에 동일한 매개변수를 선언할 수 있습니다.

예를 들어, `title` 메타데이터 값을 경로 매개변수 `item_id`에 선언하려면 다음과 같이 입력할 수 있습니다:

```Python hl_lines="10"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

!!! note "참고"
    경로 매개변수는 경로의 일부여야 하므로 언제나 필수적입니다.

Kasiyer 💁  "Hamburgerler hazır !" 🍔 dediğinde ve görüntülenen numara sizin numaranız olduğunda hemen koşup hamburgerlerinizi almaya çalışmıyorsunuz. Biliyorsunuzki kimse sizin hamburgerlerinizi 🍔 çalmayacak çünkü sıra sizin.

## Pathのインポート

まず初めに、`fastapi`から`Path`をインポートします:

```Python hl_lines="1"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

## メタデータの宣言

パラメータは`Query`と同じものを宣言することができます。

例えば、パスパラメータ`item_id`に対して`title`のメタデータを宣言するには以下のようにします:

```Python hl_lines="8"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

!!! note "備考"
    パスの一部でなければならないので、パスパラメータは常に必須です。
