How to get Wikipedia page from Wikidata Id?
You have to use MediaWiki API with action=wbgetentities:
https://www.wikidata.org/w/api.php?action=wbgetentities&format=xml&props=sitelinks&ids=Q19675&sitefilter=frwiki
where:
ids=Q19675- Wikidata item IDsitefilter=frwiki- to get page title only for French Wikipedia
For your example response will be:
<api success="1">
<entities>
<entity type="item" id="Q19675">
<sitelinks>
<sitelink site="frwiki" title="Musée du Louvre">
<badges/>
</sitelink>
</sitelinks>
</entity>
</entities>
</api>
First, with Python and Pip, install the Wikipedia library but also the Wikidata library:
https://pypi.org/project/Wikidata/
Now, imagine you got your WikidataId (here: Q1617977, for example), so you can read the entity.data from you WikidataId.
Just print the entity.data, you will see it is similar to a json.
So you can iterate into to get other information from your WikidataId, doing something like:
['sitelinks']['frwiki']['url']
from wikidata.client import Client
import wikipedia
client = Client()
entity = client.get('Q1617977', load=True)
url = entity.data['sitelinks']['frwiki']['url']
print(url)
In python you could do something like this:
def get_wikipedia_url_from_wikidata_id(wikidata_id, lang='en', debug=False):
import requests
from requests import utils
url = (
'https://www.wikidata.org/w/api.php'
'?action=wbgetentities'
'&props=sitelinks/urls'
f'&ids={wikidata_id}'
'&format=json')
json_response = requests.get(url).json()
if debug: print(wikidata_id, url, json_response)
entities = json_response.get('entities')
if entities:
entity = entities.get(wikidata_id)
if entity:
sitelinks = entity.get('sitelinks')
if sitelinks:
if lang:
# filter only the specified language
sitelink = sitelinks.get(f'{lang}wiki')
if sitelink:
wiki_url = sitelink.get('url')
if wiki_url:
return requests.utils.unquote(wiki_url)
else:
# return all of the urls
wiki_urls = {}
for key, sitelink in sitelinks.items():
wiki_url = sitelink.get('url')
if wiki_url:
wiki_urls[key] = requests.utils.unquote(wiki_url)
return wiki_urls
return None
If you run get_wikipedia_url_from_wikidata_id("Q182609", lang='en') you get back:
'https://en.wikipedia.org/wiki/Jacques_Rogge'
If you run get_wikipedia_url_from_wikidata_id("Q182609", lang=None) you get back:

Once you get the Wikipedia url you should also resolved them with their redirection.
def get_redirect_urls(wikipedia_url_ids, retry=0, max_retry=10, backoff=2, debug=False):
import json
import requests
import time
wikipedia_url_ids_encoded = [requests.utils.quote(x) for x in wikipedia_url_ids]
request_url=r'https://en.wikipedia.org/w/api.php?action=query&titles={}&&redirects&format=json'.format("|".join(wikipedia_url_ids_encoded))
if debug: print(request_url)
response = requests.get(request_url)
if retry == max_retry:
return None
if response.status_code == 429:
# Too many requests
wait = backoff * (2 ** (retry - 1))
time.sleep(wait)
return get_redirect_urls(wikipedia_url_ids, retry=retry + 1)
response_json = json.loads(response.text)
if debug: print(response_json)
if 'query' not in response_json:
raise RuntimeError(f'impossible to parse request: {request_url}, response: {reponse_json}')
normalized = {x['from']: x['to'] for x in response_json.get('query').get('normalized', [])}
redirects = {x['from']: x['to'] for x in response_json.get('query').get('redirects', [])}
normalized_url_id_dict = {x: normalized.get(x, x) for x in wikipedia_url_ids}
return {x: redirects[normalized_url_id_dict[x]].replace(' ', '_') for x in wikipedia_url_ids
if normalized_url_id_dict[x] in redirects}
If you remove the hostname prefix and only extract the identifier of the page from the URL path you could get the dictionary of redirected URLs.

"Park Jung-suk (video game player)", "Valley Children's Hospital",
"Troop Officers Military College",
"Hobbs_&_Shaw", "Schematic_Records", "Ethan_Klein", "Hobbs & Shaw"], debug=True)
Would print and return:
