Это обычная Python функция.

**FastAPI** будет вызывать её каждый раз при получении `GET` запроса к URL "`/`".

В данном случае это асинхронная функция.

Вы также можете определить ее как обычную функцию вместо `async def`:

### `HTMLResponse`

Usa algum texto ou sequência de bytes e retorna uma resposta HTML. Como você leu acima.

### `PlainTextResponse`

Usa algum texto ou sequência de bytes para retornar uma resposta de texto não formatado.
