### Working with Python *enumerations*

The value of the *path parameter* will be an *enumeration member*.

#### Compare *enumeration members*

You can compare it with the *enumeration member* in your created enum `ModelName`:

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

#### Get the *enumeration value*

### Trabajando con los *enumerations* de Python

El valor del *parámetro de path* será un *enumeration member*.

#### Compara *enumeration members*

Puedes compararlo con el *enumeration member* en el enum (`ModelName`) que creaste:

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

#### Obtén el *enumeration value*

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.

```Python hl_lines="1  6-9"
{!../../docs_src/path_params/tutorial005.py!}
```

### Trabalhando com os *enumeration* do Python

O valor do *parâmetro da rota* será um *membro de enumeration*.

#### Compare *membros de enumeration*

Você pode comparar eles com o *membro de enumeration* no enum `ModelName` que você criou:

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

 *
 * <h2>Relationship with Java compiler standard location</h2>
 * This enumeration is closely related to the {@link JavaFileManager.Location} enumerations.
 * A difference is that the latter enumerates input and output files, while {@code JavaPathType}
 * enumerates only input dependencies. Another difference is that {@code JavaPathType} contains
 * some enumeration values used only at runtime and therefore not available in {@code javax.tool},

```Python hl_lines="1 6 7 8 9"
{!../../docs_src/path_params/tutorial005.py!}
```
