### Passo 5: retorne o conteúdo

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Você pode retornar um `dict`, `list` e valores singulares como `str`, `int`, etc.

Você também pode devolver modelos Pydantic (você verá mais sobre isso mais tarde).

    response2.body.close()

    assertThat(recordedEvents).doesNotContain("DnsStart")
    assertThat(recordedEvents).doesNotContain("DnsEnd")

                    final ZipEntry entry = new ZipEntry(id + "/" + filePath.getFileName().toString());

- Improved how the API server responds to **list** requests where the response format negotiates to Protobuf. List responses in Protobuf are marshalled one element at the time, drastically reducing memory needed to serve large collections. Streaming list responses can be disabled via the `StreamingCollectionEncodingToProtobuf` feature gate. ([#129407](https://github.com/kubernetes/kubernetes/pull/129407),...

```JSON
{
  "detail": "Item not found"
}
```

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.
