Solve the following python programming problem given the following code:
def group_identifier(tlist) : 
    def _consume_cycle(tl, i) : 
        x = itertools.cycle (((lambda y : (y.match (T.Punctuation, '.') or (y.ttype is T.Operator) or (y.ttype is T.Wildcard))), (lambda y : ((y.ttype in (T.String.Symbol, T.Name, T.Wildcard, T.Literal.Number.Integer, T.Literal.Number.Float)) or isinstance (y, (sql.Parenthesis, sql.Function)))))) 
        for t in tl.tokens [i :] : 
            if (t.ttype is T.Whitespace) : 
                (yield t) 
                continue 
if next (x) (t) : 
                (yield t) 
else : 
                raise StopIteration 
def _next_token(tl, i) : 
        t1 = tl.token_next_by_type (i, (T.String.Symbol, T.Name, T.Literal.Number.Integer, T.Literal.Number.Float)) 
        t2 = tl.token_next_by_instance (i, (sql.Function, sql.Parenthesis)) 
        if (t1 and t2) : 
            i1 = tl.token_index (t1) 
            i2 = tl.token_index (t2) 
            if (i1 > i2) : 
                return t2 
else : 
                return t1 
else : 
            if t1 : 
                return t1 
else : 
                return t2 
[group_identifier (sgroup) for sgroup in tlist.get_sublists () if (not isinstance (sgroup, sql.Identifier))] 
    idx = 0 
    token = _next_token (tlist, idx) 
    while token : 
        identifier_tokens = ([token] + list (_consume_cycle (tlist, (tlist.token_index (token) + 1)))) 
        if (identifier_tokens and (identifier_tokens [(- 1)].ttype is T.Whitespace)) : 
            identifier_tokens = identifier_tokens [: (- 1)] 
if (not ((len (token) == 1) and (isinstance (identifier_tokens [0], (sql.Function, sql.Parenthesis)) or (identifier_tokens [0].ttype in (T.Literal.Number.Integer, T.Literal.Number.Float))))) : 
            group = tlist.group_tokens (sql.Identifier, identifier_tokens) 
            idx = (tlist.token_index (group) + 1) 
else : 
            idx += 1 
token = _next_token (tlist, idx) 

    
    

    Fix the buggy line: if (not ((len (token) == 1) and (isinstance (identifier_tokens [0], (sql.Function, sql.Parenthesis)) or (identifier_tokens [0].ttype in (T.Literal.Number.Integer, T.Literal.Number.Float))))) :
