Quick Start

Create First Presentation

from pptx import Presentation

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Hello World"
prs.save('presentation.pptx')
print("✓ Presentation created!")

Add Content Slide

from pptx import Presentation

prs = Presentation()

# Title slide
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "My Presentation"
slide.placeholders[1].text = "Subtitle here"

# Content slide
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Agenda"
slide.placeholders[1].text = "• Point 1\n• Point 2\n• Point 3"

prs.save('output.pptx')

Slide Layouts

from pptx import Presentation

prs = Presentation()

# Available layouts (indices may vary by template)
# 0 - Title Slide
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Title"
slide.placeholders[1].text = "Subtitle"

# 1 - Title and Content
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Heading"
slide.placeholders[1].text = "Content here"

# 2 - Section Header
slide = prs.slides.add_slide(prs.slide_layouts[2])

# 3 - Two Content
slide = prs.slides.add_slide(prs.slide_layouts[3])

# 4 - Comparison
slide = prs.slides.add_slide(prs.slide_layouts[4])

# 5 - Title Only

Error Handling

Common Errors

Error: "Placeholder not found"

# Solution: Check layout has the placeholder
slide = prs.slides.add_slide(prs.slide_layouts[0])
if len(slide.placeholders) > 1:
    slide.placeholders[1].text = "Subtitle"

Error: "Image not found"

# Solution: Check file exists before adding
import os
if os.path.exists('image.jpg'):
    slide.shapes.add_picture('image.jpg', Inches(1), Inches(1))
else:
    print("Image file not found!")

Error: "Chart data error"

# Solution: Ensure data categories and series match
chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3']  # Must match series length
chart_data.add_series('Revenue', (100, 150, 200))

Best Practices

1. Use Master Slides for Consistency

# Edit slide master for consistent branding
slide_master = prs.slide_master
title_layout = slide_master.slide_layouts[0]

2. Keep File Size Manageable

# Compress images before adding
from PIL import Image
img = Image.open('large.jpg')
img.thumbnail((1920, 1080))
img.save('compressed.jpg', quality=85)

3. Use Standard Fonts

# Use fonts available on most systems
title.text_frame.paragraphs[0].font.name = 'Arial'  # Safe choice

4. Limit Animations

# python-pptx has limited animation support
# Create simple, clean slides instead

Testing Your Setup

# test-pptx.py
from pptx import Presentation
from pptx.util import Inches
import os

print("Testing PPTX setup...")

# Test 1: Create basic presentation
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Test Presentation"
prs.save('test-output.pptx')
assert os.path.exists('test-output.pptx')
print("✓ Basic creation test passed")

# Test 2: Add content
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Content Slide"
slide.placeholders[1].text = "Test content"
prs.save('test-output.pptx')
print("✓ Content addition test passed")

# Test 3: Load and verify
prs = Presentation('test-output.pptx')
assert len(prs.slides) == 2
print("✓ Load and verify test passed")

# Cleanup
os.remove('test-output.pptx')
print("✓ All tests passed!")

Run test:

python test-pptx.py
