Average Mask 2
==============

Implement the following Python function in the module :mod:`mask_avg2` (file :file:`mask_avg2.py`):   

    ``mask_avg2(l, l2, l3)``
    
such that

    **given** ``l``, ``l2``, ``l3`` lists of :class:`float` with same length 
    
    **modifies** ``l`` by replacing every value ``v``  by the average of the two values placed in the same position in ``12`` and ``l3``, but **only** when this value is bigger than ``v``. The new value must be rounded to 1 decimal.

For example:

.. literalinclude:: mask_avg2-test.txt
    :language: python3
    :start-after: ---- ini
    :end-before: ---- fi
   
Doctests are available at the :download:`mask_avg2-test.txt` file.
