        Parameters:
        -----------

            The source to execute. If not specified, the input buffer will be

            an execution has occurred.

        interactive : bool, optional (default False)

            Whether the console is to treat the source as having been manually

Executes source or the input buffer, possibly prompting for more
        input.

        Parameters:
        -----------
        source : str, optional

            The source to execute. If not specified, the input buffer will be
            used. If specified and 'hidden' is False, the input buffer will be
            replaced with the source before execution.

        hidden : bool, optional (default False)

            If set, no output will be shown and the prompt will not be modified.
            In other words, it will be completely invisible to the user that
            an execution has occurred.

        interactive : bool, optional (default False)

            Whether the console is to treat the source as having been manually
            entered by the user. The effect of this parameter depends on the
            subclass implementation.

        Raises:

        RuntimeError
            If incomplete input is given and 'hidden' is True. In this case,
            it is not possible to prompt for more input.

        Returns:
        --------
        A boolean indicating whether the source was executed.
