It returns a pair of values (conn,address)socket.bind() Used to bind to the address that is specified as a parametersocket.close() Used to bind to the address that is specified as a parametersocket.connect() Used to mark the socket as closedsocket.listen()Used to connect to a remote address specified as theparameterImportant methods of the socket modulewww.edureka.co/python
