Introducing Server-Sent Events in Python

Server-Sent Events (SSE) provide a simpler alternative to WebSockets for one-way, server-to-client real-time communication. SSE uses standard HTTP connections with automatic reconnection and native browser support, making it ideal for live dashboards, notifications, and progress updates. The article demonstrates practical implementations using Python and FastAPI, including system monitoring, progress bars, and stock tickers, showing how SSE can handle complex real-time scenarios with minimal code complexity.
