TutorTurbo's Making Awesome UI (TUI) in the Terminal with Textual and Python: Build apps that live in the terminal and look incredible

Your terminal can run a real application. Not scrolling text. Panels, buttons, tables, colour, a progress bar that fills while you watch, and a mouse pointer that works.

A TUI is an application that lives inside a terminal window. This book builds them in Python with Textual , starting from one install command and ending with a complete keyboard-driven app that uses every idea in the book.

Eighteen chapters, in order, each short enough to finish in one sitting. Every code listing is a picture of code that was typed into a file and run first. Every screen picture was taken from the running program by the program itself.
