I am having trouble getting a sparql describe query to work. when I have used a sample set from DBpedia.org, the program (below) has given a result, but when i have used sample in localhost the result conatin error.

the file (.owl) in the localhost : http://localhost/exemple.owl)
i defined the localhots like thise : command : c:/pyhon34/python -m http.server dans le repertoire c:/application wich contain the hhtp server.

the program :

from SPARQLWrapper import SPARQLWrapper, RDF, JSON, POST, SELECT
result= "http://localhost:8000";

sparql = SPARQLWrapper(result)
sparql.setQuery("""
SELECT ?a ?b WHERE{ ?a rdfs:subClassOf ?b }
""")
sparql.setReturnFormat(JSON)

results = sparql.query().convert()
print(results)
