#. Write a program that exchanges (swaps) two variables ``var1`` and
   ``var2``, both ``str`` type.

   To output the values before and after the swap operation, use the
   ``print()`` function like so,

   .. code-block:: python

      print('Before:', var1, var2)
      print('After:', var1, var2)
