input: Write a function to design a basic chatbot in Python for responding to casual inquiries. The chatbot should randomly select a response from a predefined list of possible answers and print it in response to user input. The conversation should continue until the user types 'Goodbye', at which point the chatbot should print 'Goodbye!' and terminate.
  def chatbot():
      answers = ["That's a great question!", "I'm not sure, but I'll try to find out!", "That sounds interesting, tell me more!", "I have no idea, sorry!"]
      
      while True:
          user_input = input('You: ')
          if user_input == 'Goodbye':
              print('Chatbot: Goodbye!')
              break
          else:
              print('Chatbot: ', random.choice(answers))
  assert chatbot()==None
output: def chatbot():
      answers = ["That's a great question!", "I'm not sure, but I'll try to find out!", "That sounds interesting, tell me more!", "I have no idea, sorry!"]
      
      while True:
          user_input = input('You: ')
          if user_input == 'Goodbye':
              print('Chatbot: Goodbye!')
              break
          else:
              print('Chatbot: ', random.choice(answers))
