PyScript Enables Seamless Python and JavaScript Integration for In-Browser Coding and Dynamic Web Interaction
Launched by Anaconda in April 2022, PyScript is an innovative technology that brings Python to the web as a scripting language for WebAssembly-enabled browsers.
WebAssembly, a high-performance runtime standard supported by all major browsers, allows languages like C, C++, and Rust to run natively in the browser. Since Python’s reference implementation is written in C, earlier projects like Pyodide were able to port Python to WebAssembly.
PyScript, however, goes beyond simply porting Python. It aims to create a comprehensive in-browser environment where Python can be used seamlessly alongside JavaScript for web scripting. Building on Pyodide, it introduces enhanced capabilities such as importing Python standard libraries, leveraging third-party libraries, and enabling robust two-way interaction with the Document Object Model (DOM).
Currently, PyScript remains a prototype and is not yet recommended for production environments. However, developers can experiment with PyScript components and examples on its official site, exploring its potential for Python and JavaScript interoperability in the browser.
In this overview, we will dive into how PyScript allows Python to function effectively in web applications, facilitating new kinds of cross-language development.
At its core, PyScript consists of a single JavaScript include that you can add to a web page. This include loads the base PyScript runtime and automatically adds support for custom tags used in PyScript.
