## Використання `Annotated` у типі параметра `q`

Пам’ятаєте, як я раніше розповідав, що `Annotated` можна використовувати для додавання метаданих до параметрів у [Вступі до типів Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Щоб використовувати `EmailStr`, спочатку встановіть <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Переконайтесь, що Ви створили [віртуальне середовище](../virtual-environments.md){.internal-link target=_blank}, активували його, а потім встановили пакет, наприклад:

```console
$ pip install email-validator
```

or with:

```console

```

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.
