I had so much trouble getting the python tcp client to work like I wanted it to. Then I tried my hand on the async tcp client and was pleasantly surprised how simple it was.

    reader, writer = await asyncio.wait_for(asyncio.open_connection(), connect_timeout)
    line = ""
    while True: 
        line = await asyncio.wait_for(reader.readline(), read_timeout)
        if line == b"":
            break
        yield line
