## Импорт `File` { #import-file }

Импортируйте `File` и `UploadFile` из модуля `fastapi`:

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[3] *}

## Определите параметры `File` { #define-file-parameters }

Создайте параметры `File` так же, как вы это делаете для `Body` или `Form`:

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[9] *}

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<div class="termy">

```console
$ python myapp.py

</div>

but is not called when another file imports it, like in:

```Python
from myapp import app
```

Let's say your file is named `myapp.py`.
