I want to learn how to use twisted together with asyncio. I create several files to describe my problem https://gist.github.com/whalebot-helmsman/c400eb66c0bd35e406de3f8f704adf13: <https://gist.github.com/whalebot-helmsman/c400eb66c0bd35e406de3f8f704adf13:>

- I can use pure asyncio for simple case (asyncio_ex.py)

- I can use pure twisted for simple case (twisted_ex.py)

- I can await in twisted on twsited defer (twisted_await.py)

I have a problem in case I try to await in twisted for asyncio coroutine(twisted_await_asyncio.py). Program never finishes and I got only started messages

Your code is mostly correct, but you are running the default Twisted reactor. You need to use the asyncio reactor. The article Kyle linked to (https://meejah.ca/blog/python3-twisted-and-asyncio <https://meejah.ca/blog/python3-twisted-and-asyncio>) describes the necessary set-up. Hopefully in the future this will be more automatic! -g
