Textual
Textual is a Rapid Application Development framework for Python.
Build sophisticated user interfaces with a simple Python API. Run your apps in the terminal and (coming soon) a web browser!

About
Textual adds interactivity to Rich with an API inspired by modern web development.
On modern terminal software (installed by default on most systems), Textual apps can use 16.7 million colors with mouse support and smooth flicker-free animation. A powerful layout engine and re-usable components makes it possible to build apps that rival the desktop and web experience.
Compatibility
Textual runs on Linux, macOS, and Windows. Textual requires Python 3.7 or above.
Installing
Install Textual via pip:
pip install "textual[dev]"
The addition of [dev] installs Textual development tools. See the docs if you need help getting started.
Demo
Run the following command to see a little of what Textual can do:
python -m textual
