Creating TUI Applications with Textual and Python

About the Book

Learn how to create text-based user interfaces (TUIs) using Python and the amazing Textual package.

Textual is a rapid application development framework for your terminal or web browser. You can build complex, sophisticated applications in your terminal. While terminal applications are text-based rather than pixel-based, they still provide amazing user interfaces.

The Textual package allows you to create widgets in your terminal that mimic those used in a web or GUI application.

The intent of Creating TUI Applications with Textual and Python is you teach you how to use Textual to make amazing applications of your own. The first half the of the book will teach you everything you need to know to start developing a terminal application.

The book's second half has many small applications that you will learn how to create. Each chapter also includes challenges for you to complete to help cement what you learn or give you ideas for continued learning.
