Request Token Generation problem

yes Sujith, i am using the generate_session method as following. My user ID is ZT7008

data = kite.generate_session("request_token_here", api_secret="your_secret")
kite.set_access_token(data["access_token"]),

Thanks Sujith, now my request token is being generated properly on using the url.
But when I input it in generate session as following, I am getting a token is invalid or expired error.

from kiteconnect import KiteConnect
kite = KiteConnect(api_key="xxxxxxxxxxxxxxxxxxxxxxxxxx")
kite.login_url()
data = kite.generate_session("request_tokenxxxx", api_secret="xxxxxxxxxxxxxxxxxxxxxxxx")
kite.set_access_token(data["access_token"])

Error:
TokenException Traceback (most recent call last)
in ()
3 kite = KiteConnect(api_key="xxx")
4 kite.login_url()
----> 5 data = kite.generate_session("AzSKpa34L15yK7BwRIkQdQAqgkr9JGl0", api_secret="xx")
6 kite.set_access_token(data["access_token"])
