Get to grips with asyncio in Python 3
summary
Shows a hands‑built generator-based scheduler that runs cooperative coroutines over the Lucas sequence and an inefficient primality tester to demonstrate the rule that blocking calls are contagious and stall everything, fixes that by making is_prime a generator and using yield from then await, replaces bare yields with asyncio.sleep(0), then moves to real code using the asyncio event loop, create_task / ensure_future / gather, transports/protocols and a working chat server that scales to thousands of concurrent connections.
