# Tarefas em segundo plano

Você pode definir tarefas em segundo plano a serem executadas _ após _ retornar uma resposta.

Isso é útil para operações que precisam acontecer após uma solicitação, mas que o cliente realmente não precisa esperar a operação ser concluída para receber a resposta.

# Request Files

You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```
