### Sadece modern Python

Tamamiyle standartlar **Python 3.8**'nın type hintlerine dayanıyor (Pydantic'in sayesinde). Yeni bir syntax öğrenmene gerek yok. Sadece modern Python.

# Concurrencia y async / await { #concurrency-and-async-await }

Detalles sobre la sintaxis `async def` para *path operation functions* y algunos antecedentes sobre el código asíncrono, la concurrencia y el paralelismo.

## ¿Con prisa? { #in-a-hurry }

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

Si estás usando paquetes de terceros que te dicen que los llames con `await`, como:

```Python
results = await some_library()
```

FastAPI преобразует эти настройки в **JSON**, чтобы они были совместимы с JavaScript, поскольку именно это требуется Swagger UI.

## Отключить подсветку синтаксиса { #disable-syntax-highlighting }

Например, вы можете отключить подсветку синтаксиса в Swagger UI.

Без изменения настроек подсветка синтаксиса включена по умолчанию:

```Python

That's all standard Python syntax for type declarations.

Use that same standard syntax for model attributes with internal types.

So, in our example, we can make `tags` be specifically a "list of strings":

    assert isinstance(result, list)
