- Concurrency is not the same as multithreading
- Single threaded concurrency
# Generators - already in Python 2 !
- Generator - a function you can pause!
- How to implement async with generators and event loop in Python 2
# What is new in Python 3 ?
- async/await - really generators in disguise!
- asyncio library - ready made event loop and IO
- new syntax and new library are independent - you can mix and match old and new!
