input: Write a function that creates an AI-based chatbot in Python to answer simple queries about a product or service. The function should have predefined answers to certain questions and provide random responses for any other query. The chatbot should continue to engage in conversation until the user types "Goodbye".
  
  ### Function:
  
  import random
  
  answers = {
      'What is XYZ?': 'XYZ is a company that provides XYZ services.',
      'What does XYZ do?': 'XYZ helps customers find solutions to their problems.',
      'Where is XYZ located?': 'XYZ is located in ABC city.',
      'What are the benefits of using XYZ?': 'XYZ provides a quick and easy way to find solutions to your problems.'
  }
  
  def generate_response(question):
      if question in answers:
          return answers[question]
      else:
          return random.choice(['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?'])
  
  def start_chatbot():
      question = input('Welcome to XYZ. How can I help you? ')
      response = generate_response(question)
  
      while response != 'Goodbye':
          print(response)
          question = input('Is there anything else I can help you with? ')
          response = generate_response(question)
  
      print('Goodbye!')
  
  
  ### Assertions:
  
  assert generate_response('What is XYZ?') == 'XYZ is a company that provides XYZ services.'
  assert generate_response('What does XYZ do?') == 'XYZ helps customers find solutions to their problems.'
  assert generate_response('Where is XYZ located?') == 'XYZ is located in ABC city.'
  assert generate_response('What are the benefits of using XYZ?') == 'XYZ provides a quick and easy way to find solutions to your problems.'
  assert generate_response('How can I contact XYZ?') in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  
output: def start_chatbot():
      question = input('Welcome to XYZ. How can I help you? ')
      response = generate_response(question)
  
      while response != 'Goodbye':
          print(response)
          question = input('Is there anything else I can help you with? ')
          response = generate_response(question)
  
      print('Goodbye!')
