paiza.ioでpython その6

概要

paiza.ioでpythonやってみた。
練習問題やってみた。

練習問題

dbpediaをsparqlで叩け。

サンプルコード

# coding: utf-8

import json
import urllib.request

url = 'https://ja.dbpedia.org/sparql'
data = {
    "query": "SELECT DISTINCT * WHERE {<http://ja.dbpedia.org/resource/東京都> ?p ?o . } LIMIT 10"
}
headers = {
    'Accept': 'application/sparql-results+json',
    'Content-Type': 'application/x-www-form-urlencoded'
}
req = urllib.request.Request(url=url, data=urllib.parse.urlencode(data).encode('ascii'), headers=headers, method='POST')
with urllib.request.urlopen(req) as res:
    body = res.read()
print (body.decode('UTF-8'))

実行結果
