Method bind

python/python3/tornado/tcpserver.py:212–264

Binds this server to the given port on the given address. To start the server, call `start`. If you want to run this server in a single process, you can call `listen` as a shortcut to the sequence of `bind` and `start` calls. Address may be either an IP address or h

        """Binds this server to the given port on the given address.

        To start the server, call `start`. If you want to run this server in a
        single process, you can call `listen` as a shortcut to the sequence of
        `bind` and `start` calls.

        Address may be either an IP address or hostname.  If it's a hostname,
        the server will listen on all IP addresses associated with the name.
        Address may be an empty string or None to listen on all available
        interfaces.  Family may be set to either `socket.AF_INET` or
        `socket.AF_INET6` to restrict to IPv4 or IPv6 addresses, otherwise both
        will be used if available.

        The ``backlog`` argument has the same meaning as for `socket.listen
        <socket.socket.listen>`. The ``reuse_port`` argument has the same
        meaning as for `.bind_sockets`.

        This method may be called multiple times prior to `start` to listen on
        multiple ports or interfaces.

        .. versionchanged:: 4.4
           Added the ``reuse_port`` argument.

        .. versionchanged:: 6.2
           Added the ``flags`` argument to match `.bind_sockets`.

        .. deprecated:: 6.2
           Use either ``listen()`` or ``add_sockets()`` instead of ``bind()``
           and ``start()``. The ``bind()/start()`` pattern depends on
           interfaces that have been deprecated in Python 3.10 and will be
           removed in future versions of Python.
