Starlette (and **FastAPI**) are based on <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, which makes it compatible with both Python's standard library <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> and <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

FastAPI를 사용하지 않더라도, 높은 호환성 및 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>의 이점(예: *구조화된 동시성*)을 취하기 위해 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>를 사용해 비동기 응용프로그램을 작성할 수 있습니다.

### 비동기 코드의 다른 형태

파이썬에서 `async`와 `await`를 사용하게 된 것은 비교적 최근의 일입니다.

        final List<LabelTypeItem> itemList = new ArrayList<>();
        for (final LabelType labelType : labelTypeList) {
            final LabelTypeItem item = new LabelTypeItem();
            item.setLabel(labelType.getName());
            item.setValue(labelType.getValue());
            item.setPermissions(labelType.getPermissions());
            item.setVirtualHost(labelType.getVirtualHost());

## Lifespan

Puedes definir esta lógica de *startup* y *shutdown* usando el parámetro `lifespan` de la app de `FastAPI`, y un "context manager" (te mostraré lo que es en un momento).

Comencemos con un ejemplo y luego veámoslo en detalle.

Creamos una función asíncrona `lifespan()` con `yield` así:
