/// info | Información sobre `@decorator`

Esa sintaxis `@algo` en Python se llama un "decorador".

Lo pones encima de una función. Como un bonito sombrero decorativo (supongo que de ahí viene el término).

Un "decorador" toma la función de abajo y hace algo con ella.

Na saída, há uma linha com algo como:

```hl_lines="4"

```

Essa linha mostra a URL onde a sua aplicação está sendo servida, na sua máquina local.

Isso inclui o `uvloop`, a substituição de alto desempenho para `asyncio`, que fornece um grande aumento de desempenho de concorrência.

Quando você instala o FastAPI com algo como `pip install "fastapi[standard]"`, você já obtém `uvicorn[standard]` também.
