## Convert POTM to PPSX in Python

[*Aspose.Slides for Python via .NET*](/slides/python-net/) lets you convert POTM presentation templates to PPSX slide shows programmatically. Load the template and call `Presentation.save` with `SaveFormat.PPSX`.

Install the library from [PyPI](https://pypi.org/project/aspose-slides/) by using the following command:

### Console/Terminal

pip install aspose-slides
```
