input: Write a function to implement a web scraper in Python that can extract the latest stock prices from specific websites for a given list of stock symbols. If the stock price is successfully extracted, return it as a string. If the extraction fails, return "Price not available". If the input list is empty, return "No stocks provided".
  assert get_stock_price("AAPL") == "$145.54"  # assuming this is the current price
  assert get_stock_price("MSFT") == "$252.35"  # assuming this is the current price
  assert get_stock_price("FB") == "Price not available"  # assuming FB was not found
  assert get_stock_price([]) == "No stocks provided"
