Python 2.7 使用rdflib.Graph获取关于具有特殊字符的名称的类别，如；弗兰ç；“奥朗德先生”；

我正在尝试从几个人那里获取DBpedia类型。我试过rdflib。这是我的密码：

from rdflib import Graph, URIRef, RDFS
from rdflib.namespace import RDF
import urllib
import re

name = u'François Hollande'

g = Graph()
uriref = URIRef("http://dbpedia.org/resource/%s" % urllib.quote(re.sub(re.compile('\s', re.U), '_', name).encode('utf-8')))
g.parse(uriref)
for s,p,o in g:
    if (p in [
         URIRef("http://www.w3.org/2002/07/owl#sameAs"),
         RDFS.seeAlso
     ]) and (uriref != o):
        g.parse(location=o)
for s,p,o in g.triples((None, RDFuriref2.type, None)):
    print o

如您所见，我尝试查看数据库中是否存在一些“同义词”。我这样做是因为“弗朗索瓦·奥朗德”的图表将返回这个（状态为303）：

尽管如此，我的代码还是发送了一个UnicodeError。我不知道如何调用第二个资源而不提高它。如果我在python shell上手动调用它，我会得到以下结果：

谢谢你的建议

顺便说一下，我正在Ubuntu 16.04LTS上使用Python2.7。谢谢它有用吗？顺便说一下，我正在Ubuntu 16.04LTS上使用Python 2.7。谢谢有帮助吗？
