Traveler expenses
=================

The expenses of a traveler are represented in a list of sublists. In
each sublist there are one-day expenses (*float* values). The traveler is
visiting a single country and the expenses are in the currency of this
country.

Save the following functions into file :file:`expenses.py`.

#. Write function :py:func:`dayexpenses` that takes a list corresponding
   to the expenses of one day, and modifies it by adding the total spent
   on that day as the last item of the list. Examples:

   .. literalinclude:: dayexpenses.txt
      :language: python3
      :lines: 3-

   .. note::

#. Write function :py:func:`expenses` that takes a list of sublists, as
   described in the first paragraph, and the conversion value of the
   currency of the visited country in euros, and modifies the given
   list of sublists in such a way that to each sublist the total spent
   on that day in euros is added as the last item of the sublist. In
   addition, this function must return the total spent in euros on that
   trip. This function must use the previous function :py:func:`dayexpenses`.

   .. literalinclude:: expenses.txt
      :language: python3
      :lines: 3-

#. Write function :py:func:`dayhighexpense` that takes a list
   corresponding to the expenses of one day and a certain amount (all
   in the same currency), and returns the value of the first specific
   expense that exceeds that amount. If no expense exceeds the given
   amount this function must return the value 0.
