这段代码可以解决这个问题:

import rdflib
from rdflib import Graph

rdflib.plugin.register('sparql', rdflib.query.Processor,
                       'rdfextras.sparql.processor', 'Processor')
rdflib.plugin.register('sparql', rdflib.query.Result,
                       'rdfextras.sparql.query', 'SPARQLQueryResult')
g = Graph()
g.parse('PLAYERS3.owl')

query = """
SELECT * WHERE {
        ?s ?p ?o .
}
"""
for row in g.query(query):
    print row
