I don’t understand Python’s Asyncio

asyncio is supposed to implement asynchronous IO with the help of coroutines. Originally implemented as a library around the yield and yield from expressions it’s now a much more complex beast as the language evolved at the same time. So here is the current set of things that you need to know exist:

  • event loops
  • event loop policies
  • awaitables
  • coroutine functions
  • old style coroutine functions
  • coroutines
  • coroutine wrappers
  • generators
  • futures
  • concurrent futures
  • tasks
  • handles
  • executors
  • transports
  • protocols
