What is Python’s `asyncio` event loop and how does `await` affect coroutine execution?

Accepted Answer

Python's `asyncio` event loop is a single-threaded system that executes coroutines cooperatively. The `await` keyword suspends the current coroutine, allowing the event loop to run other coroutines concurrently for I/O operations without the need for multiple threads.
