A Crash Course in Python 3's asyncio
summary
A concise walkthrough of Python 3 asyncio showing how async/await turns blocking downloads into concurrently scheduled coroutines, using aiohttp for async HTTP, subprocess + ffmpeg to convert mp3 to OGG, and a play step to verify output. Code on GitLab demonstrates reading link lists, running many downloads at once, handling async context managers, and adding a simple limits concurrency mechanism; the live demo is partly faked on conference Wi‑Fi but runs locally and exposes pitfalls like awaiting the wrong object and exception handling.
