`HTTPException`, ao fundo, nada mais é do que a conjunção entre uma exceção comum do Python e informações adicionais relevantes para APIs.

E porque é uma exceção do Python, você não **retorna** (return) o `HTTPException`, você lança o (raise) no seu código.

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

And it can return anything you want.

In this case, this dependency expects:

* An optional query parameter `q` that is a `str`.
* An optional query parameter `skip` that is an `int`, and by default is `0`.

/// tip | Consejo

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

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

Puedes devolver *miembros de enum* desde tu *path operation*, incluso anidados en un cuerpo JSON (por ejemplo, un `dict`).

```Python
from datetime import date

from pydantic import BaseModel

# Объявляем параметр как `str`
# и получаем поддержку редактора кода внутри функции
def main(user_id: str):
    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python

    private PomTestWrapper buildPom(String pomPath, String... profileIds) throws Exception {
        return buildPom(pomPath, null, null, profileIds);
    }

    private PomTestWrapper buildPom(
            String pomPath, Properties systemProperties, Properties userProperties, String... profileIds)
            throws Exception {
        return buildPom(pomPath, false, systemProperties, userProperties, profileIds);
    }

### Schritt 5: den Inhalt zurückgeben { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py39.py hl[8] *}

Sie können ein `dict`, eine `list`, einzelne Werte wie `str`, `int`, usw. zurückgeben.
