En este caso, la sesión de base de datos se mantendría hasta que la response termine de enviarse, pero si no la usas, entonces no sería necesario mantenerla.

Así es como se vería:

{* ../../docs_src/dependencies/tutorial013_an_py310.py *}

El código de salida, el cierre automático de la `Session` en:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[19:21] *}

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> directly with **FastAPI**.

        Comparing two approaches to a use case side by side can make it easier to examine the
        differences between them.


        Additionally, it's very useful to us if you can provide a "straw API" — what the
        method signatures would look like, for example, even if the method and class names are still

Como isso funciona? Vamos verificar. 🤓

### Anotações de tipo e ferramentas { #type-annotations-and-tooling }

Primeiro, vamos ver como editores, mypy e outras ferramentas veriam isso.

`BaseUser` tem os campos base. Então `UserIn` herda de `BaseUser` e adiciona o campo `password`, então, ele incluirá todos os campos de ambos os modelos.

   * thus a motivated caller may be able to expose the reference to another thread that would then
   * call cancel() and be unable to cancel the delegate.
   * There are a number of ways to solve this, none of which are very pretty, and it is currently
   * believed to be a purely theoretical problem (since the other actions should supply sufficient
   * write-barriers).
