Solve the following python programming problem given the following code:
@ property 
@ memoized 
def location_rows(self) : 
    def get_location_ledger(location) : 
        stock = StockState.objects.filter (section_id = self.section_id, sql_location = location).values_list ('sql_product__product_id', 'stock_on_hand') 
        return LocationLedger (location, { product_id : soh for (product_id, soh) in stock }) 
(start, stop) = (self.page_start, (self.page_start + self.page_size)) 
    locations = self.get_locations_queryset () [stop : stop] 
    return map (get_location_ledger, locations) 

    
    

    Fix the buggy line: locations = self.get_locations_queryset () [stop : stop]

#Here is Python code to fix the buggy line: locations = self.

locations = self.get_locations_queryset () [start : stop]
