	Observe que o valor recebido pela função (e também retornado por ela) é `3`, como um Python `int`, não como uma string `"3"`.

	Então, com essa declaração de tipo, o **FastAPI** dá pra você um <abbr title="convertendo a string que veio do request HTTP em um dado Python">"parsing"</abbr> automático no request .

Но переменная вроде `user-agent` недопустима в Python.

По умолчанию `Header` преобразует символы имен параметров из символа подчеркивания (`_`) в дефис (`-`) для извлечения и документирования заголовков.

Кроме того, HTTP-заголовки не чувствительны к регистру, поэтому вы можете объявить их в стандартном стиле Python (также известном как "snake_case").

Así que, si creamos un objeto Pydantic `user_in` como:

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

y luego llamamos a:

```Python
user_dict = user_in.dict()
```

ahora tenemos un `dict` con los datos en la variable `user_dict` (es un `dict` en lugar de un objeto modelo Pydantic).

Y si llamamos a:

```Python
print(user_dict)
```

Y envían un request con un nombre de usuario `johndoe` y una contraseña `love123`.

Entonces el código de Python en tu aplicación equivaldría a algo como:

```Python
if "johndoe" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

Und sie senden eine Anfrage mit dem Benutzernamen `johndoe` und dem Passwort `love123`.

Dann würde der Python-Code in Ihrer Anwendung etwa so aussehen:

```Python
if "johndoe" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

<div class="termy">

```console
$ which python

/home/user/code/awesome-project/.venv/bin/python
```

</div>

Nếu nó hiển thị `python` binary tại `.venv/bin/python`, trong dự án của bạn (trong trường hợp `awesome-project`), thì tức là nó hoạt động. 🎉
