/// tip

You could also access the value `"lenet"` with `ModelName.lenet.value`.

///

#### Return *enumeration members* { #return-enumeration-members }

You can return *enum members* from your *path operation*, even nested in a JSON body (e.g. a `dict`).

你可以用 `model_name.value` 取得實際的值（在這個例子中是 `str`），一般而言就是 `your_enum_member.value`：

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip

你也可以用 `ModelName.lenet.value` 取得值 `"lenet"`。

///

#### 回傳「列舉成員」 { #return-enumeration-members }

你可以從「路徑操作」回傳「列舉成員」，即使是巢狀在 JSON 主體（例如 `dict`）裡。

在回傳給用戶端之前，它們會被轉成對應的值（此例為字串）：

使用 `model_name.value` 或通用的 `your_enum_member.value` 获取实际的值（本例中为 `str`）：

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | 提示

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

///

#### 返回枚举成员 { #return-enumeration-members }

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成员。

返回给客户端之前，会把枚举成员转换为对应的值（本例中为字符串）：

class ModelName(str, Enum):
    alexnet = "alexnet"
    resnet = "resnet"
    lenet = "lenet"


app = FastAPI()


@app.get("/models/{model_name}")
async def get_model(model_name: ModelName):
    if model_name is ModelName.alexnet:
        return {"model_name": model_name, "message": "Deep Learning FTW!"}

    if model_name.value == "lenet":
        return {"model_name": model_name, "message": "LeCNN all the images"}

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | Consejo

También podrías acceder al valor `"lenet"` con `ModelName.lenet.value`.

///

#### Devolver *miembros* de enumeración { #return-enumeration-members }

Gerçek değeri (bu durumda bir `str`) `model_name.value` ile veya genel olarak `your_enum_member.value` ile alabilirsiniz:

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | İpucu

`"lenet"` değerine `ModelName.lenet.value` ile de erişebilirsiniz.

///

#### *Enumeration Member*'ları Döndürelim { #return-enumeration-members }

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | Dica
Você também pode acessar o valor `"lenet"` com `ModelName.lenet.value`.
///

#### Retorne membros de enumeração { #return-enumeration-members }

Você pode retornar *membros de enum* da sua *operação de rota*, até mesmo aninhados em um corpo JSON (por exemplo, um `dict`).
