#. Create:

   #. A tuple with two integers, ``0`` and ``1``.
   #. A tuple with two strings, ``"a"`` and ``"tuple"``.
   #. A tuple with only one element, ``"a tuple"``.

      *Hint*: you can either use the syntax presented at the beginning of
      the chapter, or use a list-tuple conversion.

   #. A tuple with the integers between 0 and 99.

      *Hint*: is there some way to exploit the ``range()`` function?

#. Given ``l = [0, 1, 2]`` and ``t = (0, 1, 2)``, what is the difference
   between:

   #. First case::

       x = l
       x[0] = "ok"

   #. Second case::

       x = t
       x[0] = "ok"

#. Given the tuple::

    tup = (0, 1, 2, [3, 4, 5], 6, 7, 8)

   #. What is the type of the first element of the tuple?
   #. What is the type of the fourth element?
   #. How many elements does the tuple contain?
   #. How many elements does the inner list contain?
   #. Change the last element of the inner list to ``"last element"``.
   #. Change the last element of the tuple to ``"very last element"``. (Can you do that without resorting to tricks?)
