Reusable code for placing orders

@sujith @rakeshr -

I want to write a python function to place orders so I can set the default values like variety, exchange etc. When I want to place an order I just pass the ones that will change like trading symbol, price, quantity. I am not able to achieve that using the function mentioned below as the defaults are mentioned as string in the function definition and kite.place_order throws an error. How can I solve this problem? Is there a way to achieve this so I can reduce some code in my program.

def place_order(kite, variety='kite.VARIETY_AMO', exchange='kite.EXCHANGE_NFO', tradingsymbol=None, transaction_type='kite.TRANSACTION_TYPE_BUY', quantity=None, price=None, product='kite.PRODUCT_NRML', order_type='kite.ORDER_TYPE_LIMIT', tag='algo_trader'):
        try:
            order_id = kite.place_order(
                variety=variety,
                exchange=exchange,
                tradingsymbol=tradingsymbol,
                transaction_type=transaction_type,
                quantity=quantity,
                price=price,
                product=product,
                order_type=order_type,
                tag=tag)
        except Exception as e:
            logging.error("Unable to place order: %s", e)
            logging.info("Retrying....")
