Fix: Incorrect argument 'secret' used in multiple example files

[Adithya-bs]

Problem: Keyword Argument Mismatch

The KiteConnect.generate_session method in kiteconnect/connect.py defines its second parameter as api_secret. However, several files in the examples/ directory incorrectly use the keyword argument secret.

When a user attempts to run these examples, it results in a TypeError: generate_session() got an unexpected keyword argument 'secret'.

Affected Files

The following files currently contain this error:

• examples/simple.py
• examples/gtt_order.py
• examples/order_margins.py

To Reproduce

Run any of the affected example scripts. The execution fails at the session generation step:

data = kite.generate_session("request_token_here", secret="your_secret")
