### Paso 5: devuelve el contenido

```Python hl_lines="8"
{!../../../docs_src/first_steps/tutorial001.py!}
```

Puedes devolver `dict`, `list`, valores singulares como un `str`, `int`, etc.

También puedes devolver modelos de Pydantic (ya verás más sobre esto más adelante).

### Passo 5: retorne o conteúdo

```Python hl_lines="8"
{!../../../docs_src/first_steps/tutorial001.py!}
```

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).

		if _, ok := ownFieldsMap[joinFieldName]; ok {
			if field.Name != relation.FieldSchema.Name {
				joinFieldName = inflection.Singular(field.Name) + relField.Name
			} else {
				joinFieldName += "Reference"
			}
		}

		if len(joinReferences) > idx {
			joinFieldName = cases.Title(language.Und, cases.NoLower).String(joinReferences[idx])

    `Optional[str]` の`Optional` はFastAPIでは使用されていません（FastAPIは`str`の部分のみ使用します）。しかし、`Optional[str]` はエディタがコードのエラーを見つけるのを助けてくれます。

## Pydanticを使わない方法
