input: Write a function to demonstrate how to return two values from a Python function using a tuple. The function should assign two different values to two variables and then return them as a tuple. The returned tuple should be unpacked into two variables and printed.
  assert get_multi_values() == ('ABC', 123)
  assert value1 == 'ABC'
  assert value2 == 123
output: def get_multi_values():
      value1 = 'ABC'
      value2 = 123
      return (value1, value2)
