import asyncio: Learn Python’s AsyncIO #4 - Coroutines Under The Hood

This series of videos introduces AsyncIO to Python programmers who haven’t used it yet. After weeks of silence, Episode IV is like a new hope. Ekhem. I mean, we cover: - what Future objects are and how to use them; - how asyncio implements Future objects; - how coroutines worked in Python 3.4; - how the mighty Task brings it all together; - how coroutines work in Python 3.8; - custom awaitables; and - the most annoying gotcha of asyncio for newcomers.
