Para usar `EmailStr`, primeiro instale <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ative-o e instale-o, por exemplo:

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

ou com:

```console
$ pip install "pydantic[email]"
```

## Eine „aufrufbare“ Instanz

In Python gibt es eine Möglichkeit, eine Instanz einer Klasse „aufrufbar“ („callable“) zu machen.

Nicht die Klasse selbst (die bereits aufrufbar ist), sondern eine Instanz dieser Klasse.

Dazu deklarieren wir eine Methode `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

/// info

To use `EmailStr`, first install <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

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

or with:

```console

    remove)
        REMOVE_DIRS=true
        REMOVE_SERVICE=true
    ;;

    purge)
        REMOVE_USER_AND_GROUP=true

---> 100%
```

</div>
