### Mit Python-*<abbr title="Enumeration – Aufzählung">Enums</abbr>* arbeiten

Der *Pfad-Parameter* wird ein *<abbr title="Member – Mitglied: Einer der möglichen Werte einer Enumeration">Member</abbr> eines Enums* sein.

#### *Enum-Member* vergleichen

Sie können ihn mit einem Member Ihres Enums `ModelName` vergleichen:

```Python hl_lines="17"
{!../../../docs_src/path_params/tutorial005.py!}

        fir.findPsi()
    } ?: FirSyntheticFunctionInterfaceSourceProvider.findPsi(fir)
}

/**
 * Finds [PsiElement] which will be used as go-to referenced element for [KtPsiReference]
 * For data classes & enums generated members like `copy` `componentN`, `values` it will return corresponding enum/data class
 * Otherwise, behaves the same way as [findPsi] returns exact PSI declaration corresponding to passed [FirDeclaration]
 */

    ```

Eles serão adicionados ao esquema OpenAPI e usados pelas interfaces de documentação automática:

### Tags com Enums

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

	public static final field HEADERS Lokhttp3/logging/HttpLoggingInterceptor$Level;
	public static final field NONE Lokhttp3/logging/HttpLoggingInterceptor$Level;
	public static fun getEntries ()Lkotlin/enums/EnumEntries;
	public static fun valueOf (Ljava/lang/String;)Lokhttp3/logging/HttpLoggingInterceptor$Level;
	public static fun values ()[Lokhttp3/logging/HttpLoggingInterceptor$Level;
}

    ```

They will be added to the OpenAPI schema and used by the automatic documentation interfaces:

### Tags with Enums

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

### 声明*路径参数*

使用 Enum 类（`ModelName`）创建使用类型注解的*路径参数*：

```Python hl_lines="16"

	public static final field STALL_SOCKET_AT_START Lokhttp3/mockwebserver/SocketPolicy;
	public static final field UPGRADE_TO_SSL_AT_END Lokhttp3/mockwebserver/SocketPolicy;
	public static fun getEntries ()Lkotlin/enums/EnumEntries;
	public static fun valueOf (Ljava/lang/String;)Lokhttp3/mockwebserver/SocketPolicy;
	public static fun values ()[Lokhttp3/mockwebserver/SocketPolicy;
