League Ranker

=============

|Build Status| |PyPI - Version|

Given a collection of entrants and their scores, sort them and return their

ranked points.

The mechanism used to allocate the ranked points is a generalised form of that

used for the `Student Robotics `__ league

points (quote from the SR

`rulebook `__):

    The team with the **most** game points will be awarded 8 points

    towards the competition league. The team with the second most will

    be awarded 6. The team with the third most will be awarded 4 points,

    and the team with the fewest game points will be awarded 2 points.

    Teams whose robot was not entered into the round, or who were

    disqualified from the round, will be awarded no points.

    Tied robots will be awarded the average of the points that their

    combined positions would be awarded. Thus, three robots tied for

    first place would receive 6 points each (since this is

    ``(8+6+4)/3``).

The ranker supports an arbitrary number of entrants and zones (as long as there

are fewer entrants than zones) and will return points which follow the pattern

described above.

The points for the winning team will be 2 × the number of zones, points for

subsequent places reduce by 2 points per place. Ties are resolved as described

and as a result of the points per place reducing by two, the points for any

entrant will always be an integer.

It supports Python 3.7+.

Tests

~~~~~

Tests can be run for the current interpreter by running ``./run-tests`` or for

all supported available interpreters by running ``tox``.
