What in the World is Asyncio?
summary
Asyncio is a new standard library module that supplies a single threaded event loop, futures and coroutine helpers and the talk demonstrates using asyncio in Python 3.4 to run network clients and servers. Examples show turning a callback style web request into a linear flow with yield from coroutines to fetch and JSON decode pages, explain cooperative multitasking and the need to avoid blocking calls, and note possible but not yet widespread Twisted compatibility adapters plus a thread pool workaround for blocking libraries.
