Python Zerodha API Integration

I need a clean, production-ready Python module that connects to the Zerodha Kite Connect API and proves end-to-end functionality—from session authentication right through to placing and modifying live orders. The code should follow good object-oriented practices, handle exceptions gracefully and keep credentials secure.

The immediate goal is to:
• authenticate with my API key/secret and request token
• subscribe to market data streams via WebSocket
• fetch historical price data on demand
• place, modify and cancel orders programmatically

Please build the solution using the official kiteconnect Python package wherever possible, but feel free to improve on its abstractions if you can demonstrate clearer structure or easier reuse. A concise README that explains environment setup, required dependencies and example usage is part of the deliverable.

Once I can run the sample script locally, watch market ticks populate and see a test order execute on my Zerodha account, I will consider the job complete.
