How to handle keep alive received probe on python server

Question

In a python-written server with TCP socket defined as follows:

def create_tcp_socket(bind_address):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    sock.bind(bind_address)
    return sock
[...]
sock.accept()
sock.settimeout(SOCK_TIMEOUT)

I'd like to handle the keep-alive probe so to reset the timeout if the client is sending keep-alive probes. Currently, with the above implementation, keepalive probes are acknowledged but still, the server is dropping and closing the connection with a FIN once SOCK_TIMEOUT expires.

Is there a way in the socket python library to handle the keepalive functionality?
