推荐答案

包含示例代码可以使您更轻松地了解自己所追求的，但是请参阅

Including sample code would make it easier to know what you are after but see the documentation on querying an RDFLib graph with SPARQL.

使用rdflib-sqlalchemy中的示例自述文件，其中graph是打开图的名称.

Using the example from the rdflib-sqlalchemy README where graph is the name of the open graph.

rq = "select ?s where {?s ?p ?o} limit 10"

results = graph.query(rq)
for row in results:
    print row.s
