cotoha_api.py は次のページの python3 の CotohaApi をそのまま使っています。

自然言語処理を簡単に扱えると噂のCOTOHA APIをPythonで使ってみた

cotoha01.py
#! /usr/bin/python

import sys
import os
import json
from dotenv import load_dotenv

from cotoha_api import CotohaApi
# ----------------------------------------------------------------------
if __name__ == '__main__':

	dotenv_path = '.env'
	load_dotenv(dotenv_path)
	CLIENT_ID = os.environ.get("CLIENT_ID")
	CLIENT_SECRET = os.environ.get("CLIENT_SECRET")
	DEVELOPER_API_BASE_URL = os.environ.get("DEVELOPER_API_BASE_URL")
	ACCESS_TOKEN_PUBLISH_URL = os.environ.get("ACCESS_TOKEN_PUBLISH_URL")
# ----------------------------------------------------------------------
	# COTOHA APIインスタンス生成
	cotoha_api = CotohaApi(CLIENT_ID, CLIENT_SECRET, DEVELOPER_API_BASE_URL, ACCESS_TOKEN_PUBLISH_URL)

	# 解析対象文
	sentence = "特急はくたか"

	# 構文解析API実行
	result = cotoha_api.parse(sentence)

#	sys.stderr.write("len = %d\n" % len(result["result"]))

#	for unit in result["result"]:
#		llx = len(unit['tokens'])
#		sys.stderr.write("llx(tokens) = %d\n" % llx)

	for unit in result["result"]:
		for token in unit['tokens']:
			print(token['form'],token['pos'])
# ----------------------------------------------------------------------
.env
