input: Write a function to illustrate how to return multiple values from a Python function using different methods. The function should demonstrate how to return values using a tuple and how to return multiple values directly from the 'return' statement.
  def return_multi_values():
      value1 = "ABC"
      value2 = 123
      return value1, value2  # Using tuple
  
  def return_multi_values_2():
      value1 = "XYZ"
      value2 = 456
      return value1, value2  # Directly returning multiple values
  
  assert return_multi_values() == ("ABC", 123)
  assert return_multi_values_2() == ("XYZ", 456)
output: def return_multi_values():
      value1 = "ABC"
      value2 = 123
      return value1, value2  # Using tuple
  
  def return_multi_values_2():
      value1 = "XYZ"
      value2 = 456
      return value1, value2  # Directly returning multiple values
