Create & edit PowerPoint with python-pptx

Build real .pptx files with the open-source python-pptx library (python3 -c "import pptx"). Work in visible steps; verify before reporting done.

Workflow

1. Outline the deck: a title slide + one slide per section; note any tables, images, or speaker notes.
2. Write a Python script (heredoc via the bash tool) that builds the deck with python-pptx and saves it.
3. Verify: reopen with Presentation(path) and assert the slide count / title; print(path).
4. Report the saved path + a one-line summary.

Quality conventions

• Start with a title slide (slide_layouts[0]), then content slides (slide_layouts[1] for bullets, slide_layouts[5] "Title Only" for custom layouts/tables).
• Real bullet lists via the body placeholder's text_frame paragraphs (set .level for sub-bullets) — not one big text blob.
• Tables via slide.shapes.add_table(rows, cols, left, top, width, height); bold + fill the header row.
• Use a consistent accent color and web-safe fonts (Arial, Calibri) so the deck renders everywhere; keep ≤ ~6 bullets per slide.
• Add speaker notes with slide.notes_slide.notes_text_frame.text = "…" when useful.

Example

python3 - <<'PY'
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor
p = Presentation()
s = p.slides.add_slide(p.slide_layouts[0])
s.shapes.title.text = 'Q2 Robotics Budget'
s.placeholders[1].text = 'Funding 120k EUR — on track'

s2 = p.slides.add_slide(p.slide_layouts[5]); s2.shapes.title.text = 'Line items'
tbl = s2.shapes.add_table(3, 3, Inches(0.6), Inches(1.6), Inches(8.5), Inches(2)).table
for j, h in enumerate(['Item', 'Cost', 'Status']):
    cell = tbl.cell(0, j); cell.text = h
    cell.text_frame.paragraphs[0].runs[0].font.bold = True
for i, row in enumerate([['Actuators', '8000', 'ordered'], ['Compute', '3500', 'done']], 1):
    for j, v in enumerate(row):
        tbl.cell(i, j).text = v
p.save('deck.pptx')

assert len(Presentation('deck.pptx').slides) == 2
print('deck.pptx')

Reading / editing existing files

• Read: iterate Presentation(path).slides and each shape.text_frame.
• Edit in place: load, modify shapes/placeholders/tables, save() back; keep the existing theme, layout, and fonts.
