The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:
argument_list ::= positional_arguments [“,” starred_and_keywords]
[“,” keywords_arguments]
| starred_and_keywords [“,” keywords_arguments]
| keywords_arguments
Specifically, a keyword argument looks like this: tag=’insider trading!’
while a positional argument looks like this: …, exchange, …. The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.
Also, when an argument has a default value, such as price=None, that means you don’t have to provide it. If you don’t provide it, it will use the default value instead.
To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don’t need to use them, simply don’t specify them at all:
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity)
# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)
# Some positional, some keyword (all keywords at end):
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity, tag=’insider trading!’)
