PyKatsuyou

A Japanese verb/adjective inflections tool for python.

PyKatsuyou uses these great packages:

• igo-python (detecting verbs and adjectives)
• jaconv (convert katakana --> hiragana)
• tabulate (print a table)

Install

pip install pykatsuyou

Usage

This tool requires that you input the dictionary form of the verb/adjective. Using only hiragana may have strange results (unless it's an irregular verb).

from tabulate import tabulate
from pykatsuyou import getInflections
from igo.tagger import Tagger

tt = Tagger() # Optional

data = getInflections('する', jsonIndent=2, tt=tt)
print(data['json'])
print(data['list'])

table = getInflections('行く', dataframe=True)
print(tabulate(table, headers='keys', tablefmt='pretty'))

CLI

pykatsuyou する

pykatsuyou -h

Usage:
pykatsuyou [verb/adjective] [-h/-j/-l]
*Must use dictionary form

Options:
***A table is printed by default***
-h (--help) = outputs this text
-j (--json) = prints json
-l (--list) = prints a list

Output - 行く
