How to get Wikipedia page from Wikidata Id?

How to get Wikipedia page (in a particular language, say French) from the Wikidata Id (ex: Q19675)? The question seems obvious but strangely, I find nothing on the web. I'm looking for a url command that I could use with requests Python module, something like:

url = "https://www.wikidata.org/w/api.php?action=some_method&ids=Q19675"
r = requests.post(url, headers={"User-Agent" : "Magic Browser"})

Someone can help me?

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 ID
• sitefilter=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>
