The return value is a Server object which can be used to stop the service. If host is an empty string or None all interfaces are assumed and a list of multiple sockets will be returned (most likely one for IPv4 and another one for IPv6). The host parameter can also be a sequence (e.g. list) of hosts to bind to. family can be set to either AF_INET or AF_INET6 to force the socket to use IPv4 or IPv6. If not set it will be determined from host (defaults to AF_UNSPEC). flags is a bitmask for getaddrinfo(). sock can optionally be specified in order to use a preexisting socket object. backlog is the maximum number of queued connections passed to listen() (defaults to 100). ssl can be set to an SSLContext to enable SSL over the accepted connections. reuse_address tells the kernel to reuse a local socket in TIME_WAIT state, without waiting for its natural timeout to expire. If not specified will automatically be set to True on UNIX. reuse_port tells the kernel to allow this endpoint to be bound to the same port as other existing endpoints are bound to, so long as they all set this flag when being created. This option is not supported on Windows. ssl_handshake_timeout is the time in seconds that an SSL server will wait for completion of the SSL handshake before aborting the connection. Default is 60s. start_serving set to True (default) causes the created server to start accepting connections immediately. When set to False, the user should await Server.start_serving() or Server.serve_forever() to make the server to start accepting connections.
