The asyncio Event Loop: One Thread, Many Tasks
The asyncio event loop is a manager for a single-threaded process, juggling tasks to prevent idleness during slow I/O. It's the core of apps like FastAPI, handling network requests efficiently. The footgun is interacting with it directly; use `asyncio.run()`.
The asyncio event loop is a manager for a single-threaded process, juggling tasks to prevent idleness during slow I/O operations. It runs one task until it hits a wait (like a network call), then immediately switches to another ready task. This is the core of applications like FastAPI, enabling high concurrency for I/O-bound workloads without the overhead of multi-threading. The biggest footgun is interacting with the loop directly; modern asyncio abstracts this away, so you should almost always use `asyncio.run()`.
