También puedes declarar una clase como el tipo de una variable.

Digamos que tienes una clase `Person`, con un nombre:

{* ../../docs_src/python_types/tutorial010_py39.py hl[1:3] *}

Luego puedes declarar una variable para que sea de tipo `Person`:

{* ../../docs_src/python_types/tutorial010_py39.py hl[6] *}

Y luego, nuevamente, obtienes todo el soporte del editor:

## Use `HTTPException` { #use-httpexception }

To return HTTP responses with errors to the client you use `HTTPException`.

### Import `HTTPException` { #import-httpexception }

{* ../../docs_src/handling_errors/tutorial001_py39.py hl[1] *}

### Raise an `HTTPException` in your code { #raise-an-httpexception-in-your-code }

`HTTPException` is a normal Python exception with additional data relevant for APIs.

{* ../../docs_src/response_directly/tutorial002_py39.py hl[1,18] *}

### `HTMLResponse` { #htmlresponse }

Takes some text or bytes and returns an HTML response, as you read above.

### `PlainTextResponse` { #plaintextresponse }

Takes some text or bytes and returns a plain text response.

{* ../../docs_src/custom_response/tutorial005_py39.py hl[2,7,9] *}

### `JSONResponse` { #jsonresponse }

{* ../../docs_src/response_directly/tutorial002_py39.py hl[1,18] *}

### `HTMLResponse` { #htmlresponse }

Nimmt Text oder Bytes entgegen und gibt eine HTML-Response zurück, wie Sie oben gelesen haben.

### `PlainTextResponse` { #plaintextresponse }

Nimmt Text oder Bytes entgegen und gibt eine Plain-Text-Response zurück.

{* ../../docs_src/custom_response/tutorial005_py39.py hl[2,7,9] *}

Tienes que asegurarte de que sea único para cada operación.

{* ../../docs_src/path_operation_advanced_configuration/tutorial001_py39.py hl[6] *}

### Usar el nombre de la *path operation function* como el operationId { #using-the-path-operation-function-name-as-the-operationid }

Você precisa ter certeza que ele é único para cada operação.

{* ../../docs_src/path_operation_advanced_configuration/tutorial001_py39.py hl[6] *}

### Utilizando o nome da *função de operação de rota* como o operationId { #using-the-path-operation-function-name-as-the-operationid }

{* ../../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] *}

/// tip

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

#### Obtener el valor de *enumeración* { #get-the-enumeration-value }

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

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

/// tip | Consejo

## Use o `HTTPException` { #use-httpexception }

Para retornar ao cliente *responses* HTTP com erros, use o `HTTPException`.

### Import `HTTPException` { #import-httpexception }

{* ../../docs_src/handling_errors/tutorial001_py39.py hl[1] *}

### Lance o `HTTPException` no seu código { #raise-an-httpexception-in-your-code }
