input: Write a function to determine if a given sentence is an 'affirmative' sentence or a 'negative' sentence by identifying negation words. If the sentence contains any negation words, it is classified as 'Negative'; otherwise, it is classified as 'Affirmative'.
  assert isAffirmativeorNegative("He always comes late but I dont mind.") == "Negative"
  assert isAffirmativeorNegative("I am very happy today.") == "Affirmative"
  assert isAffirmativeorNegative("She does not like coffee.") == "Negative"
  assert isAffirmativeorNegative("We will attend the meeting tomorrow.") == "Affirmative"
  assert isAffirmativeorNegative("They never go to the gym.") == "Negative"
output: def isAffirmativeorNegative(sentence):
      negation_words = ["not", "never", "dont", "doesnt", "wont"]
      for word in sentence.split():
          if word.lower() in negation_words:
              return "Negative"
      return "Affirmative"
