I guess the key is, can a callba

If you choose the coroutine style of progra

I'd like to learn the purpose of the statement
"yield from asyncio.sleep(2)" in that example.
In particular, I'd like to know if asyn
asyncio.sleep() returns you a Future. When you yield from a future,
your coroutine blocks, until the Future completes. In the meantime,
event loop continutes to execute other things that are waiting to be
executed. The Future returned from asyncio.sleep gets completed after
specified seconds.
