Originally the code was written like this:
except socket.error, err:
print('Socket connection error... Waiting 10 seconds to retry.')
del self.sock
time.sleep(10)
try_count += 1
The intention is to catch a socket connection error, this used to be err, or something similar.
However I have seen on a previous answer that socket.error has been deprecated from 2.6 onwards.
I can also confirm that 3.4 flags an error that says it does not support this syntax.
Does anyone please know the 3.4 equivalent?

If you do intend to handle each error in a different way, then you can leave them separate as you already have. But make sure to break / return at the end of the exception block so that you don't try the next. It's done that way in the socket examples, by using a continue in the loop.
The setsockopt() function provides an application program with the means to control socket behavior. An application program can use setsockopt() to allocate buffer space, control timeouts, or permit socket data broadcasts.
Socket connection timeout High A new Python socket by default doesn't have a timeout. Its timeout defaults to None. Not setting the connection timeout parameter can result in blocking socket mode. In blocking mode, operations block until complete or the system returns an error.
The recv method receives up to buffersize bytes from the socket. When no data is available, it blocks until at least one byte is available or until the remote end is closed. When the remote end is closed and all data is read, it returns an empty byte string.
Your issue is with the syntax, not socket.error:
This python 2 code is deprecated:
except Exception, e:
In favor of
except Exception as e:
So you want:
except socket.error as err:
Indeed socket.error is deprecated in Python 3. You can now catch the superclass (OSError). And if want you can check within the except which kind of subclass of the exception was really raised (like ECONNREFUSED).
try:
...
except OSError as e:
...
