input: Write a python function to preprocess movie titles by removing punctuation and converting to lowercase.
  assert preprocess_text("The Lord of the Rings!") == ['the', 'lord', 'of', 'the', 'rings']
  assert preprocess_text("Harry Potter & the Philosopher's Stone") == ['harry', 'potter', 'the', 'philosophers', 'stone']
  assert preprocess_text("Inception") == ['inception']
output: def preprocess_text(title):
      import string
      title = title.lower()
      title = title.translate(str.maketrans('', '', string.punctuation))
      return title.split()
