Mit `File` können sie vom Client hochzuladende Dateien definieren.

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

Das, weil hochgeladene Dateien als „Formulardaten“ gesendet werden.

## Імпорт `File`

Імпортуйте `File` та `UploadFile` з `fastapi`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[3] *}

## Визначення параметрів `File`

Створіть параметри файлів так само як Ви б створювали `Body` або `Form`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Інформація

`File`  — це клас, який безпосередньо успадковує `Form`.
