def test_get_enums_resnet():

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

{* ../../docs_src/path_params/tutorial005_py39.py hl[17] *}

#### Get the *enumeration value* { #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`:

{* ../../docs_src/path_params/tutorial005_py39.py hl[20] *}

///

### *경로 매개변수* 선언

생성한 열거형 클래스(`ModelName`)를 사용하는 타입 어노테이션으로 *경로 매개변수*를 만듭니다:

{* ../../docs_src/path_params/tutorial005.py hl[16] *}

### 문서 확인

*경로 매개변수*에 사용할 수 있는 값은 미리 정의되어 있으므로 대화형 문서에서 잘 표시됩니다:

<img src="/img/tutorial/path-params/image03.png">

### 파이썬 *열거형*으로 작업하기

*경로 매개변수*의 값은 *열거형 멤버*가 됩니다.

#### *열거형 멤버* 비교

열거형 `ModelName`의 *열거형 멤버*를 비교할 수 있습니다:

///

### 声明*路径参数*

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

{* ../../docs_src/path_params/tutorial005.py hl[16] *}

### 查看文档

 API 文档会显示预定义*路径参数*的可用值：

<img src="/img/tutorial/path-params/image03.png">

### 使用 Python _枚举类型_

*路径参数*的值是枚举的元素。

#### 比较*枚举元素*

枚举类 `ModelName` 中的*枚举元素*支持比较操作：

{* ../../docs_src/path_params/tutorial005.py hl[17] *}
