seats = 20
assignments = apportionment.huntington_hill(votes, seats)

Calculating the effective number of parties using Golosov’s measure.

from voting import diversity


parties = [750, 150, 50, 50]
effective_parties = diversity.golosov(parties)

Measuring the disproportionality of democratic representation using the Sainte-Lague measure.

from voting import proportion


votes = [750, 150, 50, 50]
seats = [80, 16, 2, 2]
disproportionality = proportion.sainte_lague(votes, seats)

Determining the Droop quota

from voting import quota


votes = 1000
seats = 20
election_quota = quota.droop(votes, seats)
