### Step 3: *path operation*を作成

#### パス

ここでの「パス」とは、最初の`/`から始まるURLの最後の部分を指します。

したがって、次のようなURLでは:

```
https://example.com/items/foo
```

...パスは次のようになります:

```
/items/foo
```

/// info | "情報"

「パス」は一般に「エンドポイント」または「ルート」とも呼ばれます。

///

constraints.SafeHtml.message                = {item} peut avoir un contenu html non sécurisé.
constraints.ScriptAssert.message            = l'expression de script "{script}" n'a pas été évaluée comme vraie.
constraints.URL.message                     = {item} doit être une URL valide.
constraints.Required.message                = {item} est obligatoire.
constraints.TypeInteger.message             = {item} doit être numérique.

例えば、URL内に複数回出現するクエリパラメータ`q`を宣言するには以下のように書きます:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial011.py!}
```

そしてURLは以下です:

```
http://localhost:8000/items/?q=foo&q=bar
```

複数の*クエリパラメータ*の値`q`（`foo`と`bar`）を*path operation関数*内で*関数パラメータ*`q`としてPythonの`list`を受け取ることになります。

そのため、このURLのレスポンスは以下のようになります:

```JSON
{
  "q": [
