Por exemplo, se você tiver uma função:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

seu programa poderia executar assim:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

   * {@snippet :
   * equiv.wrap("a").equals(equiv.wrap("b")) // true
   * equiv.wrap("a").equals(equiv.wrap("hello")) // false

   * equiv.wrap(obj).equals(obj) // always false

En este ejemplo estamos usando el flujo de OAuth2 "password".

Esto es apropiado cuando estamos iniciando sesión en nuestra propia aplicación, probablemente con nuestro propio frontend.

Porque podemos confiar en ella para recibir el `username` y `password`, ya que la controlamos.

Соответствующая в FastAPI API-операция пути могла бы выглядеть так:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Посмотрите, насколько похожи `requests.get(...)` и `@app.get(...)`.
