[Twisted-Python] Mixing async/await and asyncio
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:
- 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

I can't say I've done this but I think this page is on topic.

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!
