경로 매개변수 `item_id`의 값은 함수의 `item_id` 인자로 전달됩니다.

그래서 이 예제를 실행하고 <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>로 이동하면, 다음 응답을 볼 수 있습니다:

```JSON
{"item_id":"foo"}
```

## 타입이 있는 매개변수

파이썬 표준 타입 어노테이션을 사용하여 함수에 있는 경로 매개변수의 타입을 선언할 수 있습니다:

```Python hl_lines="7"

    table.put("bar", 1, 'b');
    table.put("foo", 3, 'c');
    return unmodifiableRowSortedTable(table).rowMap();
