#. Write function :py:func:`stars1` that takes a string and, if it has
   an even number of characters, returns a string equal to the given
   one but with two stars (asterisks) in the middle. If the given
   string has an odd number of characters, this function returns a
   string equal to the given one but with a star at the beginning and
   another one at the end.
   
   Save this function into a file named ``stars1.py``. See the
   following examples:

   .. literalinclude:: test-stars1.txt
      :language: python3
      :lines: 3-

#. Write function :py:func:`stars2` that takes a string, and returns
   another string computed by interleaving stars between each pair of
   consecutive characters of the given string.

   following examples:

   .. literalinclude:: test-stars2.txt
      :language: python3
