Data wrangling in a modern terminal

This is a live presentation in terminal which I gave at PyData Prague in 2025. The presentation itself is a Python app that uses Textual to drive the display of Markdown slides and run code snippets in a terminal window.

Install & run

As a first step, clone the repository:

git clone https://github.com/janpipek/terminal-data-talk

uv & just

If you have uv and just on your system, you don't have to install anything to run the presentation. Just run:

just present

Otherwise

Just do (ideally in a virtual environment)

pip install -e .
python presentation.py
