* und finde dort das Modul `dependencies` (die Datei unter `app/dependencies.py`) ...
* und importiere daraus die Funktion `get_token_header`.

Das würde sich auf ein Paket oberhalb von `app/` beziehen, mit seiner eigenen Datei `__init__.py`, usw. Aber das haben wir nicht. Das würde in unserem Beispiel also einen Fehler auslösen. 🚨

```Python
from .routers import items, users
```

A segunda versão é uma "importação absoluta":

```Python
from app.routers import items, users
```

    when explicitly forbidden.
 *  Fix: Throw a `SSLPeerUnverifiedException` when host verification fails.
 *  Fix: MockWebServer explicitly closes sockets. (On some Android releases,
    closing the input stream and output stream of a socket is not sufficient.

    created.

Requests tem um design muito simples e intuitivo, é muito fácil de usar, com padrões sensatos. Mas ao mesmo tempo, é muito poderoso e personalizável.

É por isso que, como dito no site oficial:

> Requests é um dos pacotes Python mais baixados de todos os tempos

O jeito de usar é muito simples. Por exemplo, para fazer uma requisição `GET`, você escreveria:

```Python
response = requests.get("http://example.com/some/url")
```

   * <ol>
   *   <li>Use sendfile(2) or equivalent. Requires that both the input channel and the output
   *       channel have their own file descriptors. Generally this only happens when both channels
   *       are files or sockets. This performs zero copies - the bytes never enter userspace.
   *   <li>Use mmap(2) or equivalent. Requires that either the input channel or the output channel
