Why is mypy complaining?

"socket" has no attribute "accept" [attr-defined]

import socket

def a() -> socket.SocketType:
    ...

b = a()

c, _ = b.accept()

It seems like the accept method is present in stubs.

• I'm not sure what the difference is, but why not -> socket.socket? – Barmar Commented Jan 29 at 18:38
• 1 @Barmar socket.SocketType was already being used. I replaced them with socket.socket and that resolved the error. – Sujay Commented Jan 29 at 18:49

There is _socket which is the underlying cpython implementation (socketmodule.c) and socket (socket.py). See a related question here.

socket.SocketType is actually _socket.socket the internal class that is wrapped/subclassed by socket.socket.
Only the child class socket.socket from socket.py has the public accept method. (Which is again a wrapper for _socket.socket._accept)
