#### 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*

You can get the actual value (a `str` in this case) using `model_name.value`, or in general, `your_enum_member.value`:

```Python hl_lines="20"

#### Сравнение *элементов перечисления*

Вы можете сравнить это значение с *элементом перечисления* класса `ModelName`:

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

#### Получение *значения перечисления*

Можно получить фактическое значение (в данном случае - `str`) с помощью `model_name.value` или в общем случае `your_enum_member.value`:

```Python hl_lines="20"

```

#### 获取*枚举值*

使用 `model_name.value` 或 `your_enum_member.value` 获取实际的值（本例中为**字符串**）：

```Python hl_lines="20"
{!../../../docs_src/path_params/tutorial005.py!}
```

!!! tip "提示"

    使用 `ModelName.lenet.value` 也能获取值 `"lenet"`。

#### 返回*枚举元素*

即使嵌套在 JSON 请求体里（例如， `dict`），也可以从*路径操作*返回*枚举元素*。

返回给客户端之前，要把枚举元素转换为对应的值（本例中为字符串）：

```Python hl_lines="18  21  23"

#### 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*

Puedes obtener el valor exacto (un `str` en este caso) usando `model_name.value`, o en general, `your_enum_member.value`:

```Python hl_lines="20"

Vous pouvez comparer ce paramètre avec les membres de votre énumération `ModelName` :

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

#### Récupérer la *valeur de l'énumération*

Vous pouvez obtenir la valeur réel d'un membre (une chaîne de caractères ici), avec `model_name.value`, ou en général, `votre_membre_d'enum.value` :

```Python hl_lines="20"
