How to handle client socket connection in asyncio?

Question

Python

Good afternoon. In all manuals, the connection is made through open_connection, but in case of problems with the connection, an error falls. What are socket.connect_ex counterparts from the standard library that return codes?

async def test(message):
    reader, writer = await asyncio.open_connection(
        '127.0.0.1', 8888)

Answer 1

You can catch those exceptions first, which is logical for asyncio, timeout, cancellation.
And additionally base type OSError, for possible connection problems.
