input: Write a function to implement a basic chatbot in Python that responds to casual inquiries. The chatbot should randomly select a response from a predefined list of answers and print it when a user inputs a message. If the user inputs 'Goodbye', the chatbot should respond with 'Goodbye!' and exit the conversation.
  assert chatbot_response("How are you?") in ["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!"]
  assert chatbot_response("What is the weather like today?") in ["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!"]
  assert chatbot_response("Goodbye") == 'Goodbye!'
output: import random
  
  def chatbot_response(message):
      responses = ["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!"]
      if message == "Goodbye":
          return 'Goodbye!'
      else:
          return random.choice(responses)
