Make Your Python App Interactive With a Text User Interface (TUI)
The Real Python Podcast
Is There a Terminal Emulator?
There's no window support yet, a because it does, it will need tem a different kind of driver. It is designed so that we'll be able to build on later. So it's eunux and ma then curley, it is for now. windows and drivers will come along eventually. But for now, it's ae nix and mak.
Have you wanted to create a Python application that goes further than a command-line interface? You would like it to have a friendly interface but don’t want to make a GUI (Graphical User Interface) or web application. Maybe a TUI (Text User Interface)would be a perfect fit for the project. This week on the show, we have Will McGugan to talk about his projects Textual and Rich.
Rich is a Python library for writing rich text to the terminal with color and style. It’s a great tool if you want to display advanced content such as tables, markdown, and syntax-highlighted code. We talk about how Will started on the project and how it’s developed over the years.
We also talk about Will’s new project Textual, a TUI using much of Rich at its core. He shares how the project is coming along and what are challenges in developing this type of application. We discuss how a TUI has more in common with CSS and web development than command line or graphical interfaces.
We also have a quick announcement at the top of the show from CPython Developer in Residence Łukasz Langa about next week’s release of Python 3.10.
Course Spotlight: Rock, Paper, Scissors With Python: A Command Line Game
In this course, you’ll learn to program rock paper scissors in Python from scratch. You’ll learn how to take in user input, make the computer choose a random action, determine a winner, and split your code into functions.
