Python-pptx is a powerful library for automating PowerPoint tasks. It helps create, edit, and manage PowerPoint files programmatically.

What is python-pptx?

Python-pptx is a Python library for working with PowerPoint (.pptx) files. It allows you to generate presentations dynamically.

With python-pptx, you can add slides, insert text, images, and charts, and format presentations without manual work.

Prerequisites

Before installing python-pptx, ensure you have Python installed. Python 3.6 or later is recommended.

You may also need python-docx if working with Word documents alongside PowerPoint.

Install python-pptx

The easiest way to install python-pptx is using pip. Open your terminal or command prompt and run:

pip install python-pptx

This will download and install the latest version of the library.

Verify Installation

To confirm the installation was successful, run the following Python code:

print(pptx.__version__)

If installed correctly, this will display the version number.

Basic Usage Examples

Here's how to create a simple PowerPoint presentation:

 
from pptx import Presentation

# Create a new presentation
prs = Presentation()

# Add a title slide
title_slide = prs.slides.add_slide(prs.slide_layouts[0])
title = title_slide.shapes.title
subtitle = title_slide.placeholders[1]

title.text = "Hello, World!"
subtitle.text = "python-pptx example"

# Save the presentation
prs.save('example.pptx')

This creates a PowerPoint file with a title slide.

Advanced Features

Python-pptx supports many advanced features like adding tables, charts, and images.

For complex data handling, you might combine it with PyTables.

Adding a Chart

Here's how to add a simple chart to your presentation:

 
from pptx.chart.data import CategoryChartData

chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3', 'Q4']
chart_data.add_series('Sales', (12.7, 15.2, 18.6, 21.4))

chart = slide.shapes.add_chart(
    XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy, chart_data
).chart

Troubleshooting
