I wrote the below code

    class PygmentsHighlighter(mistune.Renderer, ):
        def block_code(self, code, lang=None):
            if (not lang):
                return ('\n<pre><code>%s</code></pre>\n' % mistune.escape(code))
            lexer = get_lexer_by_name(lang, stripall=True)
            formatter = HtmlFormatter(classprefix='highlight    ')
            return highlight(code, lexer, formatter)
    return mistune.Markdown(renderer=PygmentsHighlighter())

What's a good function header?
