## Benutzerdefinierte Header hinzufügen

Es gibt Situationen, da ist es nützlich, dem HTTP-Error benutzerdefinierte Header hinzufügen zu können, etwa in einigen Sicherheitsszenarien.

    graphs will change, but the change is both forwards and backwards

### Langkah 5: hasilkan konten

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

Anda bisa menghasilkan `dict`, `list`, nilai singular seperti `str`, `int`, dll.

Anda juga bisa menghasilkan model Pydantic (anda akan belajar mengenai ini nanti).

### 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).
