    The Wikidata LDF end point has changed and so has the Wikidata RDF. The currently working code is:


    wikidataldf = ldf.createStore("https://query.wikidata.org/bigdata/ldf")
    sparql = """
    PREFIX wdt: <http://www.wikidata.org/prop/direct/>
    SELECT ?country ?iso WHERE {
      ?country wdt:P298 ?iso
    results = rdf.sparql(wikidataldf, sparql)
