finally:

    * On n'écrit pas une application avec uniquement Uvicorn. Cela signifie que le code devrait inclure plus ou moins, au minimum, tout le code offert par Starlette (ou **FastAPI**). Et si on fait cela, l'application finale apportera les mêmes complications que si on avait utilisé un framework et que l'on avait minimisé la quantité de code et de bugs.

And then, we extend that copy `dict`, adding another key-value pair: `"id": last_record_id`:

```Python
{**note.dict(), "id": last_record_id}
```

So, the final result returned would be something like:

```Python
{
    "id": 1,
    "text": "Some note",
    "completed": False,
}
```

!!! note
    It doesn't matter what you type in the form, it won't work yet. But we'll get there.

This is of course not the frontend for the final users, but it's a great automatic tool to document interactively all your API.

It can be used by the frontend team (that can also be yourself).

It can be used by third party applications and systems.

    ```Python hl_lines="13-18"
    {!> ../../../docs_src/sql_databases/sql_app_py39/main.py!}

Então ele constrói todos aqueles _sites_ independentes MkDocs para cada linguagem, combina eles, e gera a saída final em `./site/`.

Então você poderá "servir" eles com o comando `serve`:

<div class="termy">

```console
// Use o comando "serve" após rodar "build-all"
$ python ./scripts/docs.py serve

As the path of each *path operation* has to start with `/`, like in:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

We can also add a list of `tags` and extra `responses` that will be applied to all the *path operations* included in this router.

E então esperando novamente pelas respostas voltarem.

Essa "espera" é medida em microssegundos, e ainda assim, somando tudo, é um monte de espera no final.

Por isso que faz muito mais sentido utilizar código assíncrono para APIs web.

```Python
async def do_something():
    try:
        yield something
    finally:
        some_cleanup()
```

...that way the `finally` block is run regardless of any exception that might happen.
