source_inf_form = "基本形"
print(jinf(text, inf_type, source_inf_form, "基本形"))  # 走る
print(jinf(text, inf_type, source_inf_form, "未然形"))  # 走ら
print(jinf(text, inf_type, source_inf_form, "意志形"))  # 走ろう
print(jinf(text, inf_type, source_inf_form, "命令形"))  # 走れ
print(jinf(text, inf_type, source_inf_form, "三角形"))  # ValueError: '三角形' is not a valid inflection form of '子音動詞ラ行'

pyknp integration

pyknp is the official Python binding for Jumanpp. To enable the pyknp integration, specify the extra requirement when installing Jinf:

pip install jinf[pyknp]

Morpheme objects can be used as input for Jinf as follows.

from jinf import Jinf
from pyknp import Morpheme

jinf = Jinf()

mrph = Morpheme('走る はしる 走る 動詞 2 * 0 子音動詞ラ行 10 基本形 2 "代表表記:走る/はしる"')
print(jinf.convert_pyknp_morpheme(mrph, "基本形"))  # 走る
print(jinf.convert_pyknp_morpheme(mrph, "未然形"))  # 走ら
print(jinf.convert_pyknp_morpheme(mrph, "意志形"))  # 走ろう
print(jinf.convert_pyknp_morpheme(mrph, "命令形"))  # 走れ
print(jinf.convert_pyknp_morpheme(mrph, "三角形"))  # ValueError: '三角形' is not a valid inflection form of '子音動詞ラ行'
print(jinf.convert_pyknp_morpheme(mrph, "デアル列命令形"))  # ValueError: 'デアル列命令形' is not a valid inflection form of '子音動詞ラ行'
