# Corpo - Modelos aninhados

Com o **FastAPI**, você pode definir, validar, documentar e usar modelos profundamente aninhados de forma arbitrária (graças ao Pydantic).

## Campos do tipo Lista

Você pode definir um atributo como um subtipo. Por exemplo, uma `list` do Python:

```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial001.py!}
```

Graças ao <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>, testar aplicativos **FastAPI** é fácil e agradável.

Ele é baseado no <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, que por sua vez é projetado com base em Requests, por isso é muito familiar e intuitivo.

    d) Convey the object code by offering access from a designated

Die hier aufgeführten Informationen dienen als Leitfaden und sind nicht verbindlich.

Wenn Sie beispielsweise GraphQL verwenden, führen Sie normalerweise alle Aktionen nur mit „POST“-Operationen durch.

Możesz dowolnie używać każdej operacji (metody HTTP).

Informacje tutaj są przedstawione jako wskazówka, a nie wymóg.

Na przykład, używając GraphQL, normalnie wykonujesz wszystkie akcje używając tylko operacji `POST`.

you if you distribute copies of the library or if you modify it.

  For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
