# PowerPoint decks (.pptx) **python-pptx** for everything. The library is capable, but the deck you get is only as good as your handling of two things: **layouts** and **units**. ## Layouts first — always A slide is created *from a layout*, and the layout supplies the placeholders you then fill. Guessing layout indices produces the classic broken deck: text in the wrong place, a title that is really a body box, branding that silently disappears. scripts/inspect_pptx.py template.pptx --layouts Prints every layout in the template with its index, name, and each placeholder's index, type and position. **Run this before authoring against any template**, including the default one — index 1 is "Title and Content" in the stock template but frequently something else in a corporate deck. ```python from pptx import Presentation prs = Presentation("template.pptx") # or Presentation() for the stock template layout = prs.slide_layouts[1] # verify this index with --layouts first slide = prs.slides.add_slide(layout) slide.shapes.title.text = "Q1 results" body = slide.placeholders[1] # placeholder IDX, not position in a list body.text = "Revenue up 14%" for line in ["Costs flat", "Margin improved"]: para = body.text_frame.add_paragraph() para.text = line para.level = 1 # indent level, 0-4 ``` Building on the user's template is what preserves their fonts, colours and master — always prefer it to `Presentation()` plus manual stylin
