## Recursos Adicionais

O [Tutorial - Guia de Usuário](../tutorial/index.md){.internal-link target=_blank} deve ser o suficiente para dar a você um tour por todos os principais recursos do **FastAPI**.

Na próxima seção você verá outras opções, configurações, e recursos adicionais.

down here with me!  There are no mice in the air, I'm afraid, but
you might catch a bat, and that's very like a mouse, you know.
But do cats eat bats, I wonder?'  And here Alice began to get
rather sleepy, and went on saying to herself, in a dreamy sort of
way, `Do cats eat bats?  Do cats eat bats?' and sometimes, `Do
bats eat cats?' for, you see, as she couldn't answer either
question, it didn't much matter which way she put it.  She felt

## Conclusão

Vamos ver a mesma frase com o conteúdo cima:

> Versões modernas do Python tem suporte para **"código assíncrono"** usando algo chamado **"corrotinas"**, com sintaxe **`async` e `await`**.

Isso pode fazer mais sentido agora.

Tudo isso é o que deixa o FastAPI poderoso (através do Starlette) e que o faz ter uma performance impressionante.
