how to handle close connection Exception in websockets and asyncio (Python)?
Question
I am using websockets and asyncio in Python 3.6.3 on windows cygwin.
This is my code:
It was slightly simplified for reading.
It run and outputed correctly for a while, but later nothing was printed. I pressed ctrl+C, and got this on exiting:
Exception ignored in: <generator object WebSocketCommonProtocol.close_connection at 0x6fffe9349e8>
RuntimeError: generator ignored GeneratorExit
Did it means the try catch not working? or Did I do it the wrong way?

Change it with:
except Exception:
