# Файлы и формы в запросе { #request-forms-and-files }

Вы можете определять файлы и поля формы одновременно, используя `File` и `Form`.

/// info | Информация

Чтобы получать загруженные файлы и/или данные форм, сначала установите [`python-multipart`](https://github.com/Kludex/python-multipart).

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md), активировали его, а затем установили пакет, например:
