Company vote 2
==============

Save all functions into the same file named ``company.py``.

The file :download:`votes.txt<examples/votes.txt>` contains the result
of the vote held in a company. In each line there is the name of a
shareholder, the number of shares she has, a Boolean that contains
True if she is a partner founder of the company, and another boolean
that contains True if she approves the reform proposed. The file
contains the following lines:

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

The first two lines correspond to the partner founder Dani, who has
100 shares and to the partner (not-founder) Manel, with 5 shares.
Both have approved the reform.

#. Write the function :py:func:`person` that takes a string with a line
   like that previously described and returns a tuple with a string
   representing the name, an integer representing the number of shares
   and two Booleans representing if she is a partner founder and if
   she approves the reform. Examples:

   .. literalinclude:: person.txt
      :language: python3
      :lines: 3-
             
   .. note::

       More tests are provided in file :download:`person.txt<person.txt>`

#. Write the function :py:func:`read` that takes the name of a file
   with the same format as the file described in the beginning, and
   returns a list with tuples like those described in the previous
   paragraph, one for each person of the file. This function has to
   use the previous one. Example:

   .. literalinclude:: read.txt
      :language: python3
      :lines: 3-
             
   .. note::

       More tests are provided in file :download:`read.txt<read.txt>`

- The partner founders have the right to veto. That is, if a partner
   founder votes against the reform, it is rejected. Write the
   function :py:func:`veto` that takes a list of tuples like those
   described in the previous paragraph and returns True if any partner
   founder has voted against and False otherwise. Examples:

   .. literalinclude:: veto.txt
      :language: python3
      :lines: 3-
             
   .. note::

       More tests are provided in file :download:`veto.txt<veto.txt>`
   
- The vote of each shareholder is weighted with the number of shares
   she has. Thus, the vote of a shareholder has a value of 200 if she
   has 200 shares.  Write the function :py:func:`percentage` that
   takes a list of tuples like those previously described, and returns
   the percentage of votes that have accepted the proposal. Examples:

   .. literalinclude:: percentage.txt
      :language: python3
      :lines: 3-
             
   .. note::

       More tests are provided in file :download:`percentage.txt<percentage.txt>`

#. Write the function :py:func:`company` that takes the name of a file
   with the same format as the file described in the beginning, and
   returns one of these two strings: *The reform has been approved* or
   *The reform has not been approved*. The reform will be approved if
   nobody with a right to veto has voted against it AND if more than
   half of the (weighted) votes are favourable. This function has to
   use the three previous functions. In the given example, the reform
   would have been approved since no partner founder has issued a veto
   and there are 155 votes in favour and 150 against.
