input: Write a function to visually summarize the Twitter data by plotting the tweet authors, number of likes, and number of retweets. The function should process the Twitter data to extract the relevant fields and generate the plots.
  
  
  import matplotlib.pyplot as plt
  
  def summarize_twitter_data(twitter_data):
      # Process the Twitter data to extract
      # the relevant data fields
      authors = [tweet['author'] for tweet in twitter_data]
      num_tweets = [authors.count(author) for author in set(authors)]
      tweets = [tweet['text'] for tweet in twitter_data]
      num_likes = [tweet['likes'] for tweet in twitter_data]
      num_retweets = [tweet['retweets'] for tweet in twitter_data]
      
      # Plot the tweet authors
      plt.figure(1)
      plt.xlabel('Tweet Authors')
      plt.ylabel('Number of tweets')
      plt.title('Tweet Author Summary')
      plt.bar(authors, num_tweets)
      plt.show()
  
      # Plot the number of likes
      plt.figure(2)
      plt.xlabel('Tweets')
      plt.ylabel('Number of Likes')
      plt.title('Number of Likes Summary')
      plt.bar(tweets, num_likes)
      plt.show()
  
      # Plot the number of retweets
      plt.figure(3)
      plt.xlabel('Tweets')
      plt.ylabel('Number of Retweets')
      plt.title('Number of Retweets Summary')
      plt.bar(tweets, num_retweets)
      plt.show()
  
  # Example usage:
  twitter_data = [
      {'author': 'UserA', 'text': 'Hello World', 'likes': 10, 'retweets': 5},
      {'author': 'UserB', 'text': 'Python is great!', 'likes': 20, 'retweets': 15},
      {'author': 'UserA', 'text': 'Coding is fun', 'likes': 15, 'retweets': 10},
  ]
  
  summarize_twitter_data(twitter_data)
