Are you trying to look up a name to get an address? Or just look up an
address? The easiest way would be to use a ternary if:

sock_family = sock.AF_INET if ip.version == 4 else sock.AF_INET6

But you may find it convenient to use a dedicated function for
establishing a connection, which could look up an AAAA or A record for
a name, then proceed through all addresses, attempting connections in
turn. I'm fairly sure one exists in Python, but I can't right now
remember the name.
