Você faz isso com os tipos padrão do Python moderno.

Você não terá que aprender uma nova sintaxe, métodos ou classes de uma biblioteca específica etc.

Apenas **Python** padrão.

Por exemplo, para um `int`:

```Python
item_id: int
```

ou para um modelo mais complexo, `Item`:

```Python
item: Item
```

Lo haces con tipos estándar modernos de Python.

No tienes que aprender una nueva sintaxis, los métodos o clases de un paquete específico, etc.

Solo **Python** estándar.

Por ejemplo, para un `int`:

```Python
item_id: int
```

o para un modelo `Item` más complejo:

```Python
item: Item
```

FastAPI è un web framework moderno e veloce (a prestazioni elevate) che serve a creare API con Python 3.6+ basato sulle annotazioni di tipo di Python.

Le sue caratteristiche principali sono:

The term cloud-native revolves around the idea of applications deployed as micro services, that scale well. It is not about just retrofitting monolithic applications onto modern container based compute environment. A cloud-native application is portable and resilient by design, and can scale horizontally by simply replicating. Modern orchestration platforms like Kubernetes, DC/OS make replicating and managing containers in huge clusters easier than ever.

- **Exception Handling** (`org.codelibs.core.exception`) - Runtime exception wrappers for common checked exceptions with consistent error handling

### Modern Java 21 Support
- **Pattern Matching** - Leverages modern Java pattern matching for efficient type checking and conversion
- **Switch Expressions** - Optimized implementations using switch expressions for better performance

### Just Modern Python { #just-modern-python }

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

    - 💾 [PostgreSQL](https://www.postgresql.org) as the SQL database.
- 🚀 [React](https://react.dev) for the frontend.
    - 💃 Using TypeScript, hooks, [Vite](https://vitejs.dev), and other parts of a modern frontend stack.
    - 🎨 [Chakra UI](https://chakra-ui.com) for the frontend components.
    - 🤖 An automatically generated frontend client.
    - 🧪 [Playwright](https://playwright.dev) for End-to-End testing.

### Samenvatting

Samengevat declareer je **eenmalig** de types van parameters, body, etc. als functieparameters.

Dat doe je met standaard moderne Python types.

Je hoeft geen nieuwe syntax te leren, de methods of klassen van een specifieke bibliotheek, etc.

Gewoon standaard **Python**.

Bijvoorbeeld, voor een `int`:

```Python
item_id: int

Ancak yukarıdaki adımları takip ederek, bazı performans optimizasyonları yapılabilecektir.

## Teknik Detaylar

Python'un modern versiyonlarında **`async` ve `await`** sözdizimi ile **"coroutines"**  kullanan **"asenkron kod"** desteğine sahiptir.
