## Description

Brython is a Python 3 runtime and interpreter that executes scripts directly in the web browser. It serves as a client-side environment that translates Python source code into executable JavaScript to handle frontend logic without requiring server round-trips.

The project provides a bidirectional interoperability bridge between Python and JavaScript, allowing for the integration of external JavaScript libraries. It further functions as a tool for packaging Python scripts into standalone native mobile applications for Android devices.

The runtime includes a library for programmatic manipulation of the document object model, enabling the control of HTML elements and browser events to create dynamic user interfaces. It also supports the delivery of static assets via a local server during development.
