Juste du **Python** standard.

Par exemple, pour un `int`:

```Python
item_id: int
```

ou pour un modèle `Item` plus complexe :

```Python
item: Item
```

... et avec cette déclaration unique, vous obtenez :

    * la complétion.
    * la vérification des types.

Se você leu e entendeu tudo isso, agora **você sabe muito mais** sobre ambientes virtuais do que muitos desenvolvedores por aí. 🤓

Você pode usar ferramentas simples como `htop` para ver a CPU e a RAM usadas no seu servidor ou a quantidade usada por cada processo. Ou você pode usar ferramentas de monitoramento mais complexas, que podem ser distribuídas entre servidores, etc.

## Recapitular

Você leu aqui alguns dos principais conceitos que provavelmente precisa ter em mente ao decidir como implantar seu aplicativo:

you read and understood all this, now **you know much more** about virtual environments than many developers out there. 🤓

Knowing these details will most probably be useful in a future time when you are debugging something that seems complex, but you will know **how it all works underneath**. 😎...

   * <p>Note that constructors taking a builder object cannot be tested effectively because
   * semantics of builder can be arbitrarily complex. Still, a factory class can be created in the
   * test to facilitate equality testing. For example:
   *
   * <pre>
   * public class FooTest {

   *   private static class FooFactoryForTest {

Starlette é atualmente o mais rápido framework Python testado. Somente ultrapassado pelo Uvicorn, que não é um framework, mas um servidor.

Starlette fornece toda a funcionalidade básica de um microframework web.

   *   <li>If an exception propagates out of a {@code Runnable}, it is not necessarily seen by any

You don't have to learn a new syntax, the methods or classes of a specific library, etc.

Just standard **Python**.

For example, for an `int`:

```Python
item_id: int
```

or for a more complex `Item` model:

```Python
item: Item
```

...and with that single declaration you get:

* Editor support, including:
    * Completion.
    * Type checks.
* Validation of data:

If you have a <abbr title="A group of machines that are configured to be connected and work together in some way.">cluster</abbr> of machines with **Kubernetes**, Docker Swarm Mode, Nomad, or another similar complex system to manage distributed containers on multiple machines, then you will probably want to **handle replication** at the **cluster level** instead of using a **process manager** (like Uvicorn with workers) in each container.
