This caused me a lot of headaches (broken test) before figuring out what the heck was wrong: =)

>>> import socket
>>> s = socket.socket()
>>> s.type
<SocketKind.SOCK_STREAM: 1>
>>> s.setblocking(0)
>>> s.type
>>> s.setblocking(1) 
>>> s.type
<SocketKind.SOCK_STREAM: 1>

getsockopt() on the other hand always tells the truth:

>>> s.getsockopt(socket.SOL_SOCKET, socket.SO_TYPE)
1 I suppose we can do that in the "type" property of the Python socket class.
It appears the type is set in socket init:
...and it's changed later in setblocking:

Is this a duplicate of Issue 21327? There is some discussion there and a patch to add get_socket_type that excludes SOCK_NONBLOCK.

Woo! I completely forgot I already bumped into this and that I even filed a ticket for it.
