// tagKey returns the tag-based key to use in the pkgCache.

// The tags list, which came from go/build's Package.AllTags,

이 모든 것은 타입 선언을 위한 표준 파이썬 문법입니다.

내부 타입을 갖는 모델 어트리뷰트에 대해 동일한 표준 문법을 사용하세요.

마찬가지로 예제에서 `tags`를 구체적으로 "문자열의 리스트"로 만들 수 있습니다:

{* ../../docs_src/body_nested_models/tutorial002.py hl[14] *}

## 집합 타입

그런데 생각해보니 태그는 반복되면 안 되고, 고유한(Unique) 문자열이어야 할 것 같습니다.

그리고 파이썬은 집합을 위한 특별한 데이터 타입 `set`이 있습니다.

그렇다면 `Set`을 임포트 하고 `tags`를 `str`의 `set`으로 선언할 수 있습니다:

{* ../../docs_src/body_nested_models/tutorial003.py hl[1,14] *}

    }

    @Override
    public Map<R, Map<C, V2>> rowMap() {
      return Maps.transformValues(fromTable.rowMap(), row -> Maps.transformValues(row, function));
    }

    @Override
    public Map<C, Map<R, V2>> columnMap() {
      return Maps.transformValues(
          fromTable.columnMap(), column -> Maps.transformValues(column, function));
    }
  }

  /**

    public static final String ELEVATE_WORD_READING = "reading";
    /** Key for elevate word fields. */
    public static final String ELEVATE_WORD_FIELDS = "fields";
    /** Key for elevate word tags. */
    public static final String ELEVATE_WORD_TAGS = "tags";
    /** Key for elevate word roles. */
    public static final String ELEVATE_WORD_ROLES = "roles";

    /** Array settings for elevate words. */
    protected ArraySettings arraySettings;

So brauchen Sie vorher nicht zu wissen, wie die Feld-/Attribut-Namen lauten (wie es bei Pydantic-Modellen der Fall wäre).

Das ist nützlich, wenn Sie Schlüssel empfangen, deren Namen Sie nicht bereits kennen.

---

Ein anderer nützlicher Anwendungsfall ist, wenn Sie Schlüssel eines anderen Typs haben wollen, z. B. `int`.

### 🚮 🛃 `tags`, `responses`, & `dependencies`

👥 🚫 ❎ 🔡 `/items` 🚫 `tags=["items"]` 🔠 *➡ 🛠️* ↩️ 👥 🚮 👫 `APIRouter`.

```Python hl_lines="30-31" title="app/routers/items.py"

Use a mesma sintaxe padrão para atributos de modelo com tipos internos.

Portanto, em nosso exemplo, podemos fazer com que `tags` sejam especificamente uma "lista de strings":


{* ../../docs_src/body_nested_models/tutorial002.py hl[14] *}

## Tipo "set"


Mas então, quando nós pensamos mais, percebemos que as tags não devem se repetir, elas provavelmente devem ser strings únicas.

## FastAPI App with Tags { #fastapi-app-with-tags }

In many cases, your FastAPI app will be bigger, and you will probably use tags to separate different groups of *path operations*.

For example, you could have a section for **items** and another section for **users**, and they could be separated by tags:

{* ../../docs_src/generate_clients/tutorial002_py39.py hl[21,26,34] *}

<img src="/img/tutorial/generate-clients/image05.png">

## App FastAPI com Tags

Em muitos casos seu app FastAPI será maior, e você provavelmente usará tags para separar diferentes grupos de *operações de rota*.

Por exemplo, você poderia ter uma seção para **items** e outra seção para **users**, e elas poderiam ser separadas por tags:

{* ../../docs_src/generate_clients/tutorial002_py39.py hl[21,26,34] *}

    /** Pattern for extracting charset from meta tags. */
    protected Pattern metaCharsetPattern = Pattern.compile("<meta.*content\\s*=\\s*['\"].*;\\s*charset=([\\w\\d\\-_]*)['\"]\\s*/?>",
            Pattern.MULTILINE | Pattern.CASE_INSENSITIVE);

    /**
     * Pattern for HTML tags.
     */
    protected Pattern htmlTagPattern = Pattern.compile("<[^>]+>");
