Python Live Option Chain Fetcher

I need a Python script that fetches the live options chain from Zerodha's Kite platform and exports it to an Excel sheet.

The data points required are:
- Strike price, bid price, and ask price
- Open interest and volume
- Implied volatility and last traded price
- Change in open interest (OI)
- Greeks
- Last traded price (LTP)

The ideal candidate should have experience with:
- Python programming
- Working with APIs, specifically Zerodha's Kite API
- Data manipulation and exporting to Excel (using libraries like pandas)
- Familiarity with options trading concepts and terminologies

Please ensure the script is well-documented and user-friendly.
