## Arquivo de upload opcional

Você pode definir um arquivo como opcional utilizando as anotações de tipo padrão e definindo o valor padrão como `None`:

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

## `UploadFile` com Metadados Adicionais

Você também pode utilizar `File()` com `UploadFile`, por exemplo, para definir metadados adicionais:

# Archivos de Request

Puedes definir archivos que serán subidos por el cliente utilizando `File`.

/// info | Información

Para recibir archivos subidos, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo y luego instalarlo, por ejemplo:

```console
