input: Write a function to find the average word length in a given text.
  assert find_average_word_length("Hello world") == 5.0
  assert find_average_word_length("I love programming") == 6.0
  assert find_average_word_length("Python is amazing") == 5.33
output: def find_average_word_length(text):
      words = text.split()
      total_length = sum(len(word) for word in words)
      average_length = total_length / len(words)
      return round(average_length, 2)
