### Create an `Enum` class

Import `Enum` and create a sub-class that inherits from `str` and from `Enum`.

By inheriting from `str` the API docs will be able to know that the values must be of type `string` and will be able to render correctly.

### Crea una clase `Enum`

Importa `Enum` y crea una sub-clase que herede desde `str` y desde `Enum`.

Al heredar desde `str` la documentación de la API podrá saber que los valores deben ser de tipo `string` y podrá mostrarlos correctamente.

        $this: VALUE_PARAMETER name:<this> type:kotlin.Enum<<root>.Direction>
      FUN FAKE_OVERRIDE name:hashCode visibility:public modality:FINAL <> ($this:kotlin.Enum<<root>.Direction>) returnType:kotlin.Int [fake_override]
        overridden:
          public final fun hashCode (): kotlin.Int declared in kotlin.Enum
        $this: VALUE_PARAMETER name:<this> type:kotlin.Enum<<root>.Direction>

const GO_EVP_AEAD* _goboringcrypto_EVP_aead_aes_256_gcm_tls12(void);
enum go_evp_aead_direction_t {
	go_evp_aead_open = 0,
	go_evp_aead_seal = 1
};
int _goboringcrypto_EVP_AEAD_CTX_init_with_direction(GO_EVP_AEAD_CTX*, const GO_EVP_AEAD*, const uint8_t*, size_t, size_t, enum go_evp_aead_direction_t);

// #include <openssl/bn.h>

### Criando uma classe `Enum`

Importe `Enum` e crie uma sub-classe que herde de `str` e de `Enum`.

Por herdar de `str` a documentação da API vai ser capaz de saber que os valores devem ser do tipo `string` e assim ser capaz de mostrar eles corretamente.

```

否则，`/users/{user_id}` 将匹配 `/users/me`，FastAPI 会**认为**正在接收值为 `"me"` 的 `user_id` 参数。

## 预设值

路径操作使用 Python 的 <abbr title="Enumeration">`Enum`</abbr> 类型接收预设的*路径参数*。

### 创建 `Enum` 类

导入 `Enum` 并创建继承自 `str` 和 `Enum` 的子类。

通过从 `str` 继承，API 文档就能把值的类型定义为**字符串**，并且能正确渲染。

然后，创建包含固定值的类属性，这些固定值是可用的有效值：

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

### Création d'un `Enum`

Importez `Enum` et créez une sous-classe qui hérite de `str` et `Enum`.

En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.
