Solve the following python programming problem given the following code:
def entities_unescape(text) : 
    def fixup(m) : 
        text = m.group (0) 
        if (text [: 2] == '&#') : 
            try : 
                if (text [: 3] == '&#x') : 
                    return unichr (int (text [3 : (- 1)], 16)) 
else : 
                    return unichr (int (text [2 : (- 1)])) 
except ValueError : 
                pass 
else : 
            try : 
                if (text [1 : (- 1)] == 'amp') : 
                    text = '&amp;amp;' 
else : 
                    if (text [1 : (- 1)] == 'gt') : 
                        text = '&amp;gt;' 
else : 
                        if (text [1 : (- 1)] == 'lt') : 
                            text = '&amp;lt;' 
else : 
                            text = unichr (htmlentitydefs.name2codepoint [text [1 : (- 1)]]) 
except KeyError : 
                pass 
return text 
return re.sub ('&#?\\w+;', text, text) 

    
    

    Fix the buggy line: return re.sub ('&#?\\w+;', text, text)
