Solve the following python programming problem given the following code:
@ property 
def rows(self) : 
    rows = [] 
    if self.config ['location_id'] : 
        sp = SQLLocation.objects.get (location_id = self.config ['location_id']).supply_point_id 
        ss = StockState.objects.filter (sql_product__is_archived = False, case_id = sp, product_id__in = self.config ['products']) 
        for stock in ss : 
            def calculate_months_remaining(stock_state, quantity) : 
                consumption = stock_state.get_monthly_consumption () 
                if ((consumption is not None) and (consumption > 0) and (quantity is not None)) : 
                    return (float (quantity) / float (consumption)) 
else : 
                    if (quantity == 0) : 
                        return 0 
return None 
rows.append ([stock.sql_product.name, decimal_format (stock.stock_on_hand), float_format (calculate_months_remaining (self, stock.stock_on_hand))]) 
return rows 

    
    

    Fix the buggy line: rows.append ([stock.sql_product.name, decimal_format (stock.stock_on_hand), float_format (calculate_months_remaining (self, stock.stock_on_hand))])

#Here is Python program to fix the buggy line: rows.

rows.append ([stock.sql_product.name, decimal_format (stock.stock_on_hand), float_format (calculate_months_remaining (stock, stock.stock_on_hand))])
