The goal of the code is to retrieve options data for a specific stock ticker and expiration date using the yfinance library in Python.
The code formats the options chain data neatly and saves the data into two CSV files: _calls.csv and _puts.csv.
Each row in the CSV files includes details such as contract symbol, last trade timestamp, strike price, bid/ask prices, volume, open interest, implied volatility, among others.
This script can be useful for options backtesting, volatility screening, and automated reporting by leveraging real-time options data and Python's capabilities.
