New submission from Karthikeyan Singaravelan <tir.kar...@gmail.com>:
I guess the TimeoutError exception needs to be imported from asyncio.exceptions
and not from asyncio.futures that causes AttributeError while instantiating a
connection with happy eyeballs.
./python.exe -m asyncio
asyncio REPL 3.9.0a2+ (heads/master:068768faf6, Dec 23 2019, 18:35:26)
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin
Use "await" directly instead of "asyncio.run()".
Type "help", "copyright", "credits" or "license" for more information.
>>> import asyncio
>>> conn = await asyncio.open_connection("localhost", port=8000,
>>> happy_eyeballs_delay=1)
