Brython
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.
Features
- In-Browser Python Runtimes - Provides a complete Python 3 runtime that executes directly within the web browser.
- Bytecode Compilation - Implements a process to transform Python source code into executable bytecode for browser execution.
- Python Interpreters - Implements an interpreter that translates Python code into browser-executable instructions for interactive web pages.
