How to use Brython: A guide to writing Python for the frontend

Python, traditionally known as a backend language, can be utilized for frontend development through libraries like Brython, which acts as a Python-to-JavaScript compiler, enabling developers to write client-side code in Python that is compiled into HTML, CSS, and JavaScript. Brython allows Python code execution in the browser, providing access to browser APIs and enabling DOM manipulation while interacting with existing JavaScript libraries. To integrate Brython, developers can use pip for installation or include it via CDN in HTML pages. While JavaScript remains central to web development, Brython offers Python developers the advantage of leveraging their existing skills for frontend tasks without needing to extensively learn JavaScript. Alternatives to Brython, such as Skulpt, Transcrypt, Pyodide, and PyPy.js, also facilitate Python use in frontend settings, each with unique features like WebAssembly compilation or small file sizes, though some, like PyPy.js, have limitations due to size or inactivity.
