Yury Selivanov asyncawait and asyncio in Python 3 6 and beyond PyCon 2017

"Speaker: Yury Selivanov
The talk overviews async/await, asynchronous generators and comprehensions in Python 3.6 and the asyncio module. We'll discuss when and how asyncio should be used in a modern applications and services, what is uvloop, and what asyncio frameworks and libraries one should use. I'll share our ideas about where asyncio is headed and what to expect in Python 3.7.

Another great talk, Yuri. 👍

Great to see the PythonRust integration!

Why were some keywords added in Python for Async/Await when the concurrency model could have been implemented as functions in a separate library (loosely coupled), which is done by some programming languages ( kzbin.info/www/bejne/jnbKmpWffcl9qrM )?

[@lawrencedoliveiro9104]

4:11 something else that’s missing: being able to asynchronously assign a new value to a property, e.g. something like await obj.prop = value

[@rohithill]

When would we need this? Only case I can think of is: obj.prop = await value which is already done.

I still don’t know how use async/await in python...

[@ChrisLasher]

Isn't it a little unfair to downplay curio and trio because they're "not mainstream," yet hype up tokio, a more nascent library that hinges on integration with a completely different - and admittedly not mainstream - programming language? To my eyes, tokio carries more risk as a project than curio or trio. tokio is an exciting, interesting project, however let's give a little more respect to Python's "mad scientist", David Beazley, for demonstrating via implementation​ that a *pure Python* async framework can involve less complexity than asyncio, and give better performance.

[@tarcisioe]

I do like curio a lot, but I would recommend trio as a more "secure" alternative since curio is clearly somewhat of a playground to Beazley and its README still clearly claims it is experimental and only supports Unix systems. In 3.7 asyncio is also much more usable and well documented as well.

After listening this talk I still dont know what async/await actually IS.
