How can I use Python to create a PowerPoint presentation from a template?

Creating a PowerPoint presentation from a template using Python is possible thanks to a library named python-pptx. Here is a step-by-step guide on how you can do it:

1. Installation: First, you will need to install the library. You can do this using pip:

   pip install python-pptx

2. Import the Library: Once installed, import the library in your Python script like so:

   from pptx import Presentation

3. Load the Template: You can load your desired PowerPoint template using the Presentation class. If ‘template.pptx’ is the name of your template, you would load it as follows:

   prs = Presentation('template.pptx')

4. Add a Slide: To add a slide, you need to add a slide layout first. Use the slide layouts provided in your template. If you want to use the first layout of your template, you can do so like this:

   slide_layout = prs.slide_layouts[0]
       slide = prs.slides.add_slide(slide_layout)

5. Add Text: To add text to your slide, you need to add a text box first. You can then add text to this text box. Here’s how you can add a title and a subtitle to your slide:

   title = slide.shapes.title
       title.text = "This is a title"
       subtitle = slide.placeholders[1]
       subtitle.text = "This is a subtitle"

6. Save the Presentation: Finally, you can save your presentation like so:

   prs.save('new_presentation.pptx')

This is a basic guide on how you can create a PowerPoint presentation from a template using Python. python-pptx has many more features that allow you to add images, charts, tables, and more to your slides. You can view the full documentation here.
