* Will have the best performance, as it doesn't have much extra code apart from the server itself.
    * You wouldn't write an application in Uvicorn directly. That would mean that your code would have to include more or less, at least, all the code provided by Starlette (or **FastAPI**). And if you did that, your final application would have the same overhead as having used a framework and minimizing your app code and bugs.

### Restart After Crash

But in those cases with really bad errors that crash the running **process**, you would want an external component that is in charge of **restarting** the process, at least a couple of times...

!!! tip

* **Modify some DNS records**.
    * For this, the renewal program needs to support the APIs of the DNS provider, so, depending on the DNS provider you are using, this might or might not be an option.
* **Run as a server** (at least during the certificate acquisition process) on the public IP address associated with the domain.
    * As we said above, only one process can be listening on a specific IP and port.

```Python

```

Вот и все.

Это аннотации типов:

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial002.py!}
```

Это не то же самое, что объявление значений по умолчанию, например:

```Python
    first_name="john", last_name="doe"
```

Это другая вещь.

```Python
    first_name, last_name
```

на:

```Python
    first_name: str, last_name: str
```

Ось і все.

Це "type hints":

```Python hl_lines="1"
{!../../../docs_src/python_types/tutorial002.py!}
```

Це не те саме, що оголошення значень за замовчуванням, як це було б з:

```Python
    first_name="john", last_name="doe"
```

Це зовсім інше.

    * Sie hängt von `query_extractor` ab und weist den von diesem zurückgegebenen Wert dem Parameter `q` zu.
* Sie deklariert außerdem ein optionales `last_query`-Cookie, ein `str`.
    * Wenn der Benutzer keine Query `q` übermittelt hat, verwenden wir die zuletzt übermittelte Query, die wir zuvor in einem Cookie gespeichert haben.
