mystring is already an IP address, sorry for not mentioning that.
The point is that ternary if; I've been scouring around the internet and there's a million different variations on the same idea. 
I'm completely flabberghasted it's not a simple property within the object though, e.g. ip.sock_family.

Was this a deliberate decision by the Python devs or can I try an RFE for that?

Well you've already got socket.create_connection(), which (I think) does perform that lookup.
