Scrape Finology Ticker Symbols

I need a clean, one-off scrape of every stock ticker symbol listed on the site Ticker.finology.in. The final deliverable is a single CSV file that contains, at minimum, the ticker code; including the corresponding company name is welcome if it can be captured in the same pass.

Please use any reliable web-scraping stack you prefer—Python with requests/BeautifulSoup or Selenium is fine as long as the script respects the site’s structure and returns accurate, deduplicated data. I’m only looking for a single run, so scheduling or cron logic isn’t necessary; clarity, correctness, and a well-commented script matter more.

Acceptance criteria:
• CSV opens without errors and lists every active ticker currently shown on Ticker.finology.in.
• No blank rows or duplicate symbols.
• Include the script you used so I can re-run it if the site layout stays unchanged.
