Make Your Python App Interactive With a Text User Interface (TUI)
The Real Python Podcast
Then I'm Trying to Parse a Coud.
Exmel was often better than pythonr high level languages. It's kind of like templating, i entemplated a coud. I think its gossipbing years since i did this, but i think that r m text templets,. But it's actually the logic that's an exime o, and it's not too rebose.
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.
