input: Write a function to implement a web scraper in Python that extracts and prints the top ten trending YouTube videos from the YouTube trending page. The function should use the `requests` and `BeautifulSoup` libraries to make a request to the YouTube trending page, parse the page content, and then extract and print the titles of the top ten trending videos. If the page does not load or if there are fewer than ten videos, the function should handle the error gracefully.
  assert extract_trending_videos()
  # Expected output: Prints the titles of the top ten trending YouTube videos.
  assert extract_trending_videos() if requests.get("https://www.youtube.com/feed/trending").status_code == 200 else print("Error loading page")
  # Expected output: Handles the error if the page does not load.
output: def extract_trending_videos():
      import requests
      from bs4 import BeautifulSoup
      
      url = "https://www.youtube.com/feed/trending"
      response = requests.get(url)
      
      if response.status_code != 200:
          return
      
      soup = BeautifulSoup(response.text, 'html.parser')
      video_titles = soup.find_all('a', {'class': 'yt-simple-endpoint style-scope yt-formatted-string'})
      
      for i in range(min(10, len(video_titles))):
          print(video_titles[i].text)
