input: Write a function to implement a web scraper in Python that extracts the top ten trending YouTube videos. The function should make a request to the YouTube trending page, parse the content using BeautifulSoup, and then extract and print the titles of the top ten trending videos.
  assert extract_top_trending_videos()
  import requests
  from bs4 import BeautifulSoup
  
  def extract_top_trending_videos():
      # make a request to get the page content
      page = requests.get("https://www.youtube.com/feed/trending")
      
      # parse the page content
      soup = BeautifulSoup(page.content, 'html.parser')
      
      # extract the list of trending videos
      trending_videos = soup.find_all(class_='expanded-shelf-content-item-wrapper')
      
      # return the titles of the top ten trending videos
      return [video.find(class_='yt-uix-tile-link').get('title') for video in trending_videos[:10]]
  
  # Test cases
  assert extract_top_trending_videos() != []
  assert "video title" in extract_top_trending_videos()
output: import requests
  from bs4 import BeautifulSoup
  
  def extract_top_trending_videos():
      page = requests.get("https://www.youtube.com/feed/trending")
      soup = BeautifulSoup(page.content, 'html.parser')
