## AI overview

A tutorial on Python asynchronous programming, explaining how event loops, coroutines, async and await enable a single-threaded program to handle slow I/O without blocking. It progresses from synchronous code and generators to concurrent task execution with asyncio, using examples compatible with Python 3.11 and later.

## Source excerpt

Learn how Python async programming works. Write async functions with async and await, and run slow I/O operations concurrently with asyncio.
