PEP 3156

PEP 3156 is a proposal to enhance Python's support for asynchronous programming, allowing developers to write code that can handle many tasks simultaneously without blocking. It introduces a standardized way to create, manage, and run asynchronous functions and tasks, making programs more efficient and responsive—especially for I/O-bound operations like web requests or database interactions. Essentially, it provides the tools for Python to better manage multiple operations at once, improving performance and scalability in applications that require handling many connections or data streams concurrently.
