Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:

{* ../../docs_src/path_operation_configuration/tutorial002b_py39.py hl[1,8:10,13,18] *}

## Resumo e descrição { #summary-and-description }

Você pode adicionar um `summary` e uma `description`:

Поэтому в интерактивной документации будет вся информация и из этих зависимостей:

<img src="/img/tutorial/dependencies/image01.png">

## Простое использование { #simple-usage }

Если посмотреть, *функции обработки пути* объявляются для использования всякий раз, когда *путь* и *операция* совпадают, и тогда **FastAPI** заботится о вызове функции с корректными параметрами, извлекая данные из запроса.

Die interaktive Dokumentation enthält also auch alle Informationen aus diesen Abhängigkeiten:

<img src="/img/tutorial/dependencies/image01.png">

## Einfache Verwendung { #simple-usage }

import org.junit.jupiter.api.Test;

/**
 * Tests for SpnegoConstants interface.
 * Verifies constant values, modifiers, types, and structural properties.
 */
class SpnegoConstantsTest {

    // Simple OID format: numbers separated by dots (at least one dot)
    private static final Pattern OID_PATTERN = Pattern.compile("\\d+(?:\\.\\d+)+");

    @Test
    @DisplayName("Constant values match expected OIDs")

# Primeros Pasos { #first-steps }

El archivo FastAPI más simple podría verse así:

{* ../../docs_src/first_steps/tutorial001_py39.py *}

Copia eso en un archivo `main.py`.

## Déclarer des types

Vous venez de voir là où les types sont généralement déclarés : dans les paramètres de fonctions.

C'est aussi ici que vous les utiliseriez avec **FastAPI**.

### Types simples

Vous pouvez déclarer tous les types  de Python, pas seulement `str`.

Comme par exemple :

* `int`
* `float`
* `bool`
* `bytes`
