Esta página lhe ensinará como usar **ambientes virtuais** e como eles funcionam.

Se você estiver pronto para adotar uma **ferramenta que gerencia tudo** para você (incluindo a instalação do Python), experimente <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">uv</a>.

## Criar um Projeto

Primeiro, crie um diretório para seu projeto.

* Fornecer diretamente 2 interfaces _web_ de documentação interativa.

---

Nós arranhamos apenas a superfície, mas você já tem idéia de como tudo funciona.

Experimente mudar a seguinte linha:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...de:

```Python
        ... "item_name": item.name ...
```

...para:

 * Classes or methods annotated with this annotation may be changed / removed without notice.

 * @since 4.0.0

@Experimental
@Documented
@Retention(RetentionPolicy.CLASS)
