Nicholas Tollervey - Lessons learned with asyncio ("Look ma, I wrote a distributed hash table!") [EuroPython 2015] [22 July 2015] [Bilbao, Euskadi, Spain] This talk introduces the asyncio module. I'll cover what it's for, how it works and describe how I used it to write a real-world networked application (a distributed hash table). We'll explore the event loop, coroutines, futures and networking with examples from my code. This won't be an exhaustive exposition. Rather, attendees will grasp enough of asyncio to continue with their own studies. By the end of this introductory talk I hope attendees will want to learn more about asyncio and perhaps give it a try in their own projects.
