Temperatures
============

We have a number of temperatures measured on different dates for a set of automatic weather stations from *Meteocat* (Meteorological Service of Catalonia - meteocat.cat). For example:

.. literalinclude:: tpt_sumup-test.txt
     :language: python3
     :start-after: --input-ini
     :end-before: --input-fi
    
where we have two lists:

      - ``estL`` which is a list with the names of the station populations (:class:`str`)
      - ``tempL`` which is a list of lists where each sublist contains two components:
     
         - a :class:`str` with the date
         - a :class:`list` that contains a :class:`tuple` for each of the stations of ``estL`` and in the same order. This tuple contains three :class:`float` corresponding to the average, minimum and maximum temperatures measured on that date in that station.

Implement the following function in the :mod:`tpt.py` module (file :file:`tpt.py`):

      .. py:function:: tpt_sumup(estL, tempL)

such that

      **given** ``estL``, ``tempL`` which are :class:`list` as described above,
        
      **returns** a :class:`list` where, for each date of ``tempL`` contains a list with the following 4 data:
     
         - the date (:class:`str`)
         - the average temperature (:class:`float`) of the average temperatures of all stations, rounded to 2 decimal places
         - :class:`tuple`, with the minimum temperature of all minimums (:class:`float`) and the station the :class:`str` comes from. In the event that the minimum of the minimums has been given with more than one station, the first one that appears in the list must be returned.
         - the same for the maximum temperature.
        
For example, given the input lists in the example above, the correct list to return would be:

.. literalinclude:: tpt_sumup-test.txt
     :language: python3
     :start-after: --output-ini
     :end-before: --output-fi

The doctests are available in :download:`tpt_sumup-test.txt <tpt_sumup-test.txt>`.

.. note:: We recommend to implement and call an axiliar function such that, given a list of temperatures like the second component of  ``tempL`` returns the following five data: 
    
    - the average of all the temperature averages
    - the minimim of all the temperature minimums
    - the index of that minimum
    - the maximum of all the temperature maximums
    - the index of that maximum
