Rearranging slides in Python involves using the 'python-pptx' library to programmatically modify the order of slides within a PowerPoint presentation. This allows users to automate the process of organizing slides, enabling efficient customization and restructuring of presentations. The 'python-pptx' library simplifies slide manipulation by providing a high-level API, making it accessible to developers for various presentation-related tasks. Whether it's reordering existing slides, creating new presentations, or updating slide content, 'python-pptx' empowers users to efficiently manage and enhance PowerPoint presentations through Python scripting.

To rearrange slides in Python, you can use various libraries and tools that handle presentations. One of the popular libraries for working with PowerPoint presentations is python-pptx. With python-pptx, you can create, modify, and rearrange slides in a PowerPoint presentation. Here's a step-by-step guide on how to do it:

Make sure you have python-pptx installed in your Python environment. If you don't have it yet, you can install it using pip:

Step 3. Load the PowerPoint presentation:

presentation = Presentation("path_to_your_presentation.pptx")

The slides in python-pptx are stored in a list. To rearrange slides, you can use Python's list indexing and slicing. For example, if you want to move the slide at index from_idx to the position of index to_idx, you can use the following code:

def move_slide(presentation, from_idx, to_idx):

    slides = list(presentation.slides._sldIdLst)

    # Update slide IDs in the XML to match the new order

    slide_id_list = [slide.slide_id for slide in slides]

    presentation.slides._sldIdLst.clear()

        presentation.slides._sldIdLst.append(slide_id)

move_slide(presentation, from_idx=2, to_idx=0)  # Move slide at index 2 to the beginning

After rearranging the slides, you should save the modified presentation to keep the changes.

presentation.save("path_to_modified_presentation.pptx")

Make sure to replace "path_to_your_presentation.pptx" with the actual path to your PowerPoint presentation file and "path_to_modified_presentation.pptx" with the desired output file path.

Please note that python-pptx allows you to perform various other operations on PowerPoint presentations, such as adding new slides, modifying content, applying styles, etc. You can explore more of its capabilities in the official documentation: https://python-pptx.readthedocs.io/en/stable/index.html

Always remember to create backup copies of your original presentation before performing any modifications to avoid accidental data loss.

In conclusion, the ability to rearrange slides in Python using the 'python-pptx' library offers a powerful and efficient way to automate the organization and customization of PowerPoint presentations. With its user-friendly API, developers can easily modify slide order, create new presentations, and update slide content, providing flexibility and control over the presentation creation process. By leveraging the 'python-pptx' library, users can streamline their workflow, save time, and enhance the overall presentation management experience, making it a valuable tool for working with PowerPoint files programmatically.

Rearrange slides in Python using the python-pptx library and modify PowerPoint presentation order programmatically with ease and precision.

This works a bit differently and is not exactly the same as described in the original question.


Here Scala is in a separate module, that means scala can call the kotlin code without problems, since it’s just using a compiled library. Kotlin on the other hand can’t use the scala code, because it’s not yet compiled and you can’t add a dependency on the scala code without getting a circular dependency structure.


The original question is whether you can use scala, kotlin and java in the same module as you can do with only kotlin and java combined. This is not possible as yole explained.
