## 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__`:

## `python-jose` のインストール

PythonでJWTトークンの生成と検証を行うために、`python-jose`をインストールする必要があります：

<div class="termy">

```console
$ pip install python-jose[cryptography]

---> 100%
```

</div>

In der Dokumentation für ASGI-Middlewares von Drittanbietern wird Ihnen wahrscheinlich gesagt, etwa Folgendes zu tun:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

    if not value or not should_convert(var,
                                       parsed_args.blacklist,
                                       parsed_args.whitelist_prefix):
      continue

    # In Python, MSYS, Linux-like paths are automatically read as Windows paths
    # with forward slashes, e.g. 'C:/Program Files', instead of
    # '/c/Program Files', thus becoming converted simply by virtue of having
    # been read.

### Импортируйте `HTTPException`

{* ../../docs_src/handling_errors/tutorial001.py hl[1] *}

### Вызовите `HTTPException` в своем коде

`HTTPException` - это обычное исключение Python с дополнительными данными, актуальными для API.

Поскольку это исключение Python, то его не `возвращают`, а `вызывают`.
