In what context?  Do you have some code that gets passed a socket object 
but it could have been created with either SOCK_STREAM or SOCK_DGRAM? 
And you want a way of determining by looking just at the object passed 
in which type it is?  (I could make other guesses, but let's start with 
that... ;-)  )

How about this:

 >>> import socket
 >>> t = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 >>> u = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
 >>> dir(t)
['__class__', .... '_sock', 'accept', 'bind', 'close'
, 'connect', 'connect_ex', 'dup', 'fileno', 'getpeername',
...'setblocking', 'setsockopt', 'settimeout', 'shutdown']

Let's see... what looks good here?

 >>> u._sock
<socket object, fd=1916, family=2, type=2, protocol=0>
 >>> t._sock
<socket object, fd=1912, family=2, type=1, protocol=0>

Maybe that type field?
