Asynchronous task execution
Use asyncio to write concurrent code using the `async` and `await` syntax. Cooperative multitasking yields control back to the event loop during I/O operations.
How it reads
await asyncio.gather(...) runs multiple coroutines concurrently
asyncio.sleep yields control back to the loop without blocking
Cloud tip: Multithreading is CPU-bound limited by the GIL in Python; asyncio is perfect for I/O-bound concurrency.
