pytrovich 0.1.0

pytrovich: a Python port of an inflector for Russian anthroponyms developed by petrovich team: https://github.com/petrovich

pytrovich is a Python 3.9+ port of petrovich library which inflects Russian names to a given grammatical case. It supports first names, last names and middle names inflections. Since version 0.0.2, gender detection is also available.

petrovich-java was the main inspiration.

The alternative (earlier) port: Petrovich (@alexeyev was not aware of it at the time of porting petrovich to Python). The only meaningful difference we have found is that it does not support gender detection.

Installation

Should be as simple as that

pip install pytrovich

Usage

Inflection

from pytrovich.enums import NamePart, Gender, Case
from pytrovich.maker import PetrovichDeclinationMaker

maker = PetrovichDeclinationMaker()
print(maker.make(NamePart.FIRSTNAME, Gender.MALE, Case.GENITIVE, "Иван"))  # Ивана
print(maker.make(NamePart.LASTNAME, Gender.MALE, Case.INSTRUMENTAL, "Иванов"))  # Ивановым
print(maker.make(NamePart.MIDDLENAME, Gender.FEMALE, Case.DATIVE, "Ивановна"))  # Ивановне

Gender detection

from pytrovich.detector import PetrovichGenderDetector

detector = PetrovichGenderDetector()
print(detector.detect(firstname="Иван"))  # Gender.MALE
print(detector.detect(firstname="Иван", middlename="Семёнович"))  # Gender.MALE
print(detector.detect(firstname="Арзу", middlename="Лутфияр кызы"))  # Gender.FEMALE

Custom rule file

You can replace default rules file with some custom one. Only JSON format is supported.

maker = PetrovichDeclinationMaker("/path/to/custom/rules.file.json")

E.g. if pytrovich fails on PetrovichDeclinationMaker creation, one may consider downloading rules.json directly from petrovich-rules repo as a fix (please create an issue if that actually happens).
