In diesem Fall wird `item_id` als `int` deklariert, also als Ganzzahl.

Вы можете объявить тип параметра пути в функции, используя стандартные аннотации типов Python.

```Python hl_lines="7"
{!../../docs_src/path_params/tutorial002.py!}
```

Здесь, `item_id` объявлен типом `int`.

/// check | "Заметка"

Это обеспечит поддержку редактора внутри функции (проверка ошибок, автодополнение и т.п.).

## Check the username

Here's a more complete example.

Use a dependency to check if the username and password are correct.

For this, use the Python standard module <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> to check the username and password.
