## 별칭 매개변수

매개변수가 `item-query`이길 원한다고 가정해 봅시다.

마치 다음과 같습니다:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

그러나 `item-query`은 유효한 파이썬 변수 이름이 아닙니다.

가장 가까운 것은 `item_query`일 겁니다.

하지만 정확히`item-query`이길 원합니다...

이럴 경우 `alias`를 선언할 수 있으며, 해당 별칭은 매개변수 값을 찾는 데 사용됩니다:

## Написание шаблонов { #writing-templates }

Затем вы можете создать шаблон в `templates/item.html`, например:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### Значения контекста шаблона { #template-context-values }

В HTML, который содержит:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

#### Um item aleatório { #a-random-item }

Com `data.items()` obtemos um <abbr title="Algo que podemos iterar com um laço for, como uma list, set, etc.">objeto iterável</abbr> com tuplas contendo a chave e o valor de cada item do dicionário.

Convertimos esse objeto iterável em uma `list` adequada com `list(data.items())`.

	VersionID string `xml:"VersionId"`
}

// Metadata metadata items implemented to ensure XML marshaling works.
type Metadata struct {
	Items []struct {
		Key   string
		Value string
	}
}

// Set add items, duplicate items get replaced.
func (s *Metadata) Set(k, v string) {
	for i, item := range s.Items {
		if item.Key == k {
			s.Items[i] = struct {
				Key   string
				Value string
			}{

///

Eso significa: "la variable `items` es una `list`, y cada uno de los ítems en esta lista es un `str`".

Al hacer eso, tu editor puede proporcionar soporte incluso mientras procesa elementos de la lista:

Sin tipos, eso es casi imposible de lograr.

Nota que la variable `item` es uno de los elementos en la lista `items`.

        assertEquals(arr.length, result.length);
        assertEquals(arr[0], result[0]);

        // Test ArrayList
        final List<String> list = new ArrayList<>();
        list.add("item1");
        list.add("item2");
        binary = SerializeUtil.fromObjectToBinary(list);
        @SuppressWarnings("unchecked")
        final List<String> resultList = (List<String>) SerializeUtil.fromBinaryToObject(binary);
