Introducing Server-Sent Events in Python

Server-Sent Events (SSE) offer a straightforward method for servers to push real-time data to clients over a single, long-lived HTTP connection. As a simpler alternative to WebSockets, SSE is well-suited for one-way, server-to-client communication use cases like live notifications and real-time data dashboards. The implementation is demonstrated using Python with the FastAPI framework, which simplifies creating streaming responses. Practical code examples show how to build an SSE endpoint to stream continuous updates, such as the current time or system performance metrics like CPU and memory usage.
