### `pptx.Presentation(pptx: 'str | IO[bytes] | None' = None) -> 'presentation.Presentation'`

Return a |Presentation| object loaded from *pptx*, where *pptx* can be
either a path to a ``.pptx`` file (a string) or a file-like object. If
*pptx* is missing or ``None``, the built-in default presentation
"template" is loaded.
