## Advanced description from docstring

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

!!! info
    In OAuth2 a "scope" is just a string that declares a specific permission required.

    It doesn't matter if it has other characters like `:` or if it is a URL.

    Those details are implementation specific.

    For OAuth2 they are just strings.

## Code to get the `username` and `password`

                }
            ]

A consulta é o conjunto de pares chave-valor que vai depois de `?` na URL, separado pelo caractere `&`.

Por exemplo, na URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...os parâmetros da consulta são:

* `skip`: com o valor `0`
* `limit`: com o valor `10`
