Coroutine Concurrency in Python 3 with asyncio
summary
Builds a minimal coroutine scheduler from scratch that runs Lucas sequence generators and a naive prime tester, shows the single-bare-yield bug and why every called function must be nonblocking, then mechanically refactors those generators into Python 3 async/await backed by asyncio, replacing yield-from → await. Covers futures/tasks, why to use ensure_future/gather, transports, protocol vs stream APIs, and a working telnet-style chatroom; about 80% code and live demo.
