"Asyncio by Example"
summary
Covers async/await basics to practical patterns using Python's asyncio (running on 3.12.4) with live Jupyter demos: explains futures vs coroutines, how create_task wraps a coroutine into a future, use of ensure_future, cancellation of infinite loops, and pause points (await/async for/async with). Introduces TaskGroup cancels siblings and newer primitives like Barriers and ExceptionGroup. Builds an async httpx client against the PokéAPI to fetch multiple Pokémon concurrently and shows the code running correctly and faster than serial awaits.
