input: Write a function to create a web scraper using Python’s Selenium that retrieves data from an online store. The function should initialize a Firefox session, navigate to a specified URL, search for a keyword ('shoes'), retrieve the list of products displayed after the search, and print the text of each product name. Finally, the function should close the browser window.
  from selenium import webdriver
  
  def scrape_products(url):
      # create a new Firefox session
      driver = webdriver.Firefox()
      driver.implicitly_wait(30)
      driver.maximize_window()
  
      # navigate to the application home page
      driver.get(url)
  
      # get the search textbox
      search_field = driver.find_element_by_name("q")
      search_field.clear()
  
      # enter search keyword and submit
      search_field.send_keys("shoes")
      search_field.submit()
  
      # get the list of elements which are displayed after the search
      # currently on result page using find_elements_by_class_name
      product_list = driver.find_elements_by_class_name("product")
  
      # iterate through each element and print the text that is
      # name of the product
      for product in product_list:
          print(product.text)
  
      # close the browser window
      driver.quit()
  
  assert scrape_products("https://www.example.com/") is None
  assert scrape_products("https://www.example.com/") is None
output:
