Comment(by each):

 > Decent level programmers can probably figure out what this code does,
 but that wouldn't be immediately obvious. And, due to the nested
 conditions it's not so easy to be confident that this code does what it's
 supposed to do from a glance.

 If nesting is the problem, there are other ways to structure it.  Could
 have a series of try...except statements with "pass" in each of the
 excepts, for instance.  Or this:

 {{{
   for family in (socket.AF_INET, socket.AF_INET6):
     try:
       a = socket.inet_pton(family, addr)
       self.family = family
       self.addr = a
       return
     except socket.error:
       continue
     except Exception as e:
       raise e

     raise socket.error('Invalid IP address')
 }}}
