(如何)我可以从套接字文件描述符中确定套接字系列

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('localhost', 8080))

sock_fd = sock.fileno()
sock_family, sock_type, sock_proto, _, sock_addr = socket.getsockname(sock_fd)

if sock_family == socket.AF_INET:
    print("Socket family: AF_INET")
elif sock_family == socket.AF_INET6:
    print("Socket family: AF_INET6")
elif sock_family == socket.AF_UNIX:
    print("Socket family: AF_UNIX")
elif sock_family == socket.AF_NETLINK:
    print("Socket family: AF_NETLINK")
else:
    print("Unknown socket family")
