Objects
=======

Let's consider a dictionary with information about a number of objects with the following format:

    - The keys are 2-component :class:`tuple`:

        - the name of the object (:class:`str`)
        - the identification number (:class:`int`)

    - The values are 3-component :class:`list`:

        - a color (:class:`str`)
        - a number of items (:class:`int`)
        - a price (:class:`float`)

For example:

    .. literalinclude:: list_objects.test
        :language: pycon
        :start-after: --ini-in
        :end-before: --fi-in

You are required to deliver the following functions in the module :mod:`objects` (file :file:`objects.py`).

------------------------------------------------------------------------------------------------

The first function is:

    .. py:function:: list_objects(objD)

such that

    **given** *objD*, a :class:`dict` as described above

    **returns** a new :class:`list` of 5-component :class:`tuple` whith all the information of that object in the key and value order, namely: the name of the object (:class:`str`), the id number (:class:`int`), the color (:class:`str`), the number of items (:class:`int`) and the price (:class:`float`).

For example:

    .. literalinclude:: list_objects.test
        :language: pycon
        :start-after: --ini-out
        :end-before: --fi-out

.. warning::

    This function must be implement using **comprehension lists**.

Doctests are available in the :download:`list_objects.test` file.

------------------------------------------------------------------------------------------------

The second function is:

    .. py:function:: sort_objects(L)

such that

    **given** *L*, a :class:`list` as the output of the previous function (described above)

    **returns** a **new** :class:`list` with the same tuples but ordered according to the following criteria (listed in decreasing priority):

        #. The color, alphabetically.
        #. The numbrer of items, increasingly.
        #. The price, decreasingly.

For example:

    .. literalinclude:: sort_objects.test
        :language: pycon
        :start-after: --ini-out
        :end-before: --fi-out

.. warning::
    This input list **must not** be modified by the function.
