How to use the saspy.SASLogLexer.SASLogLexer function in saspy

for line in lines:
            i += 1
            e = []
            if line[mva.logoffset:].startswith('ERROR'):
                e = lines[(max(i - 15, 0)):(min(i + 16, len(lines)))]
            elog = elog + e
        if len(elog) == 0 and len(output) > lst_len:   # no error and LST output
            return HTML(output)
        elif len(elog) == 0 and len(output) <= lst_len:   # no error and no LST
            color_log = highlight(log, SASLogLexer(), HtmlFormatter(full=True, style=SASLogStyle, lineseparator="<br>"))
            return HTML(color_log)
        elif len(elog) &gt; 0 and len(output) &lt;= lst_len:   # error and no LST
            color_log = highlight(log, SASLogLexer(), HtmlFormatter(full=True, style=SASLogStyle, lineseparator="<br>"))
            return HTML(color_log)
        else:   # errors and LST
            color_log = highlight(log, SASLogLexer(), HtmlFormatter(full=True, style=SASLogStyle, lineseparator="<br>"))
            return HTML(color_log + output)
