Solve the following python programming problem given the following code:
def test_ready_iterator(self) : 
    values = [1, 2] 
    def iterator() : 
        while values : 
            (yield) 
            values.pop () 
return 
self.station.register_iter (iterator) 
    for i in xrange ((len (self) + 1)) : 
        self.assertTrue (self.station.has_ready_iterators ()) 
        self.station.handle_iters () 
self.assertFalse (self.station.has_ready_iterators ()) 

    
    

    Fix the buggy line: for i in xrange ((len (self) + 1)) :
