Get / create a Mongo collection. Raises :class:`TypeError` if `name` is not an instance of :class:`str`. Raises :class:`~pymongo.errors.InvalidName` if `name` is not a valid collection name. Any additional keyword arguments will be used as options passed to the creat

        Raises :class:`TypeError` if `name` is not an instance of
        :class:`str`. Raises :class:`~pymongo.errors.InvalidName` if `name` is
        not a valid collection name. Any additional keyword arguments will be used
        as options passed to the create command. See
        :meth:`~pymongo.database.Database.create_collection` for valid
        options.

        If `create` is ``True``, `collation` is specified, or any additional
        keyword arguments are present, a ``create`` command will be
        sent, using ``session`` if specified. Otherwise, a ``create`` command
        will not be sent and the collection will be created implicitly on first
        use. The optional ``session`` argument is *only* used for the ``create``
        command, it is not associated with the collection afterward.

        :param database: the database to get a collection from
        :param name: the name of the collection to get
        :param create: If ``True``, force collection
            creation even without options being set.
        :param codec_options: An instance of
            :class:`~bson.codec_options.CodecOptions`. If ``None`` (the
            default) database.codec_options is used.
        :param read_preference: The read preference to use. If
            ``None`` (the default) database.read_preference is used.
        :param write_concern: An instance of
            :class:`~pymongo.write_concern.WriteConcern`. If ``None`` (the
            default) database.write_concern is used.
        :param read_concern: An instance of
            :class:`~pymongo.read_concern.ReadConcern`. If ``None`` (the
            default) database.read_concern is used.
        :param collation: An instance of
            :class:`~pymongo.collation.Collation`. If a collation is provided,
            it will be passed to the create collection command.
        :param session: A
            :class:`~pymongo.client_session.ClientSession` that is used with
            the create collection command.
        :param kwargs: Additional keyword arguments will
            be passed as options for the create collection command.
