Fever
=====

A file contains a record of the body temperatures of several patients
admitted to a hospital. Each line of the file corresponds to a patient
and contains the name of the patient (:class:`str`) and, separated by
colons (``':'``), a variable number of measured temperatures
(:class:`float`). An example of this kind of file is file
:download:`patients.txt<examples/patients.txt>` with this content:

.. literalinclude:: examples/patients.txt
   :language: python 

Save the following function into file ``fever.py``.

Write the function :py:func:`fever` that takes the name of a file
(:class:`str`) with the described characteristics and a threshold
(:class:`float`), and returns a :class:`list` with the names
(:class:`str`) of those patients with an average temperature strictly
greater than the given threshold. Patients in this list must be in the
same order as in the file. Examples:

   .. literalinclude:: test-fever.txt
      :language: python3
      :lines: 3-

   .. note::

      More tests are provided in file :download:`test-fever.txt`
