input: Write a function to extract the latest stock prices from specific websites using Python and web scraping techniques. The function should take a list of stock symbols as input, retrieve the current stock prices, and return the prices as strings. If the stock symbol is not found or invalid, return "Price not found" for that particular symbol.

  assert get_stock_price(["GOOG", "XYZ"])==["$2800.00", "Price not found"]
  assert get_stock_price(["AAPL"])==["$150.00"]
  assert get_stock_price([])==[]
