I wrote the below code

    if (autolinks == 'default'):
        autolinks = autolinks_simple
    if (protolinks == 'default'):
        protolinks = protolinks_simple
    pp = ('\n' if pretty_print else '')
    text = (text if ((text is None) or isinstance(text, str)) else text.decode('utf8', 'strict'))
    if (not isinstance(text, str)):
        text = str((text or ''))
    text = regex_backslash.sub((lambda m: m.group(1).translate(ttab_in)), text)
    text = text.replace('\x05', '').replace('\r\n', '\n')
    if (URL is not None):
        text = replace_at_urls(text, URL)
    if (latex == 'google'):
        text = regex_dd.sub('``\\g<latex>``:latex    ', text)
    segments = []
    def mark_code(m):
        g = m.group(0)
        if (g in (META, DISABLED_META)):
            segments.append((None, None, None, g))
            return m.group()
        elif (g == '````'):
            segments.append((None, None, None, ''))
            return m.group()
        else:
            c = (m.group('c') or '')
            p = (m.group('p') or '')
            if (('code' in allowed) and (c not in allowed['code'])):
                c = ''
            code = m.group('t').replace('!`!', '`')
            segments.append((code, c, p, m.group(0)))
        return META
    text = regex_code.sub(mark_code, text)
    links = []
    def mark_link(m):
        links.append((None if (m.group() == LINK) else m.group('s')))
        return LINK
    text = regex_link.sub(mark_link, text)
    text = local_html_escape(text)
    if protolinks:
        text = regex_proto.sub((lambda m: protolinks(*m.group('p', 'k'))), text)
    if autolinks:
        text = replace_autolinks(text, autolinks)
    strings = text.split('\n')
    def parse_title(t, s):
        hlevel = str(len(t))
        out.extend(etags[::(-1)])
        out.append(('<h%s>%s' % (hlevel, s)))
        etags[:] = [('</h%s>%s' % (hlevel, pp))]
        lev = 0
        ltags[:] = []
        tlev[:] = []
        return (lev, 'h')
    def parse_list(t, p, s, tag, lev, mtag, lineno):
        lent = len(t)
       ...

What's a good function header?
