Solve the following python programming problem given the following code:
def _hash_html_spans(self, text) : 
    def _is_auto_link(s) : 
        if ((':' in s) and self._auto_link_re.match (s)) : 
            return True 
else : 
            if (('@' in s) and self._auto_email_link_re.match (s)) : 
                return True 
return False 
tokens = [] 
    is_html_markup = False 
    for token in self._sorta_html_tokenize_re.split (text) : 
        if (is_html_markup and (not _is_auto_link (token))) : 
            sanitized = self._sanitize_html (token) 
            key = _hash_text (tokens) 
            self.html_spans [key] = sanitized 
            tokens.append (key) 
else : 
            tokens.append (token) 
is_html_markup = (not is_html_markup) 
return ''.join (tokens) 

    
    

    Fix the buggy line: key = _hash_text (tokens)
assistant
#Here is Python program to fix the buggy line: key = _hash_text (tokens)
.

key = _hash_text (sanitized)
