## Description

PyScript is a framework that enables the execution of Python code directly within a web browser. By leveraging WebAssembly, it provides a runtime environment that allows developers to perform data processing and computational logic locally, eliminating the need for a backend server to handle these tasks.

The platform distinguishes itself by bridging the gap between standard web technologies and the Python runtime. It facilitates the synchronization of data and events between the browser document object model and Python scripts, while also supporting the mounting of local or remote assets into the runtime environment.

To maintain interface responsiveness during complex operations, the framework supports offloading intensive computational tasks to background browser threads. It also allows for the integration of Python logic directly into markup through custom tags, enabling a declarative approach to building interactive web applications.
