      code_format (str, optional): Format string to render HTML. In addition to '{foreground}',
                '{background}', and '{code}', should contain '{stylesheet}' if inline_styles is ``False``.
            inline_styles (bool, optional): If ``True`` styles will be inlined in to spans, which makes files
                larger but easier to cut and paste markup. If ``False``, styles will be embedded in a style tag.
                Defaults to False.
