A Python implementation of the Schulze method.
To rank candidates, call the compute_ranks method of the schulze module. This method has the following signature and Pydoc:
def compute_ranks(candidate_names, weighted_ranks):
"""Returns the candidates ranked by the Schulze method.
Parameter candidate_names is a sequence containing all the candidate names.
Parameter weighted_ranks is a sequence of (ranks, weight) pairs.
The first element, ranks, is a ranking of the candidates. It is an array of
arrays so that we can express ties. For example, [[a, b], [c], [d, e]]
represents a = b > c > d = e.
The second element, weight, is typically the number of voters that chose
this ranking.
"""For example usage, refer to the schulze_test module. From the command line, you can run these tests like so:
$ python -m unittest schulze_test
