我目前正在尝试使用变量来创建N三元组的图形,我在分配变量时没有任何问题,但我不断收到错误消息。这是代码:
from rdflib import Namespace, URIRef, Graph
from StringIO import StringIO
xmlns = "http://www.example.org/lexicon#"
rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
lemon = "http://www.monnetproject.eu/lemon#"
graph = Graph()
F = open("new_2.txt", "r")
for line in F:
这是我分配变量的部分。这很长,我知道它有效,所以我不会包括这个。以下代码仍然是for line in F:
line1 = ''+synset_offset+'\rdf.lex_filenum\ '+lex_filenum+''
line2 = ''+synset_offset+'\lemon.ss_type\ '+ss_type+''
line3 = ''
for item in word:
line3 +=''+synset_offset+'\lemon.lexical_entry\ '+iw.next()+'/n'
line4 = ''+synset_offset+'\lemon.gloss\ '+gloss+''
line5 = ''
line6 = ''
line7 = ''
for item in S:
pointer = ip.next()
pos = iss.next()
source_target = ist.next()
line5 += ''+synset_offset+'\lemon.has_ptr\ '+pointer+'/n'
line6 += ''+pointer+'\lemon.pos\ '+pos+'/n'
line7 += ''+pointer+'\lemon.source_target\ '+source_target+'/n'
contents = '''\
'''+line1+'''
'''+line2+'''
'''+line3+'''
'''+line4+'''
'''+line5+'''
'''+line6+'''
'''+line7+''''''
tabfile = StringIO(contents)
for line in tabfile:
triple = line.split() # triple is now a list of 3 strings
triple = (URIRef(t) for t in triple) # we have to wrap them in URIRef
graph.add(triple)
print graph.serialize(format='nt')
这是我正确打印所有内容的其他代码,表明它不是不起作用的变量。
print('''<http://example.org/#'''+synset_offset+'''> <http://www.monnetproject.eu/lemon#lex_filenum> "'''+lex_filenum+'''".
<http://example.org/#'''+synset_offset+'''> <http://www.monnetproject.eu/lemon#ss_type> "'''+ss_type+'''".
<http://example.org/#'''+synset_offset+'''> <http://www.monnetproject.eu/lemon#gloss> "'''+gloss+'''".''')
for item in word:
print('''<http://example.org/#'''+synset_offset+'''> <http://www.monnetproject.eu/lemon#lex_entry> "'''+iw.next()+'''".''')
for item in S:
pointer = ip.next()
pos = iss.next()
source_target = ist.next()
print('''<http://example.org/#'''+synset_offset+'''> <http://www.monnetproject.eu/lemon#has_ptr> "'''+pointer+'''".
<http://example.org/#'''+pointer+'''> <http://www.monnetproject.eu/lemon#pos> "'''+pos+'''".
<http://example.org/#'''+pointer+'''> <http://www.monnetproject.eu/lemon#source_target> "'''+source_target+'''".''')
print('''\n''')
任何比我在这里所做的更好的想法都会受到欢迎
编辑:现在我收到了这个错误:
graph.add(triple)
File "/usr/lib/python2.7/site-packages/rdflib-4.1_dev-py2.7.egg/rdflib/graph.py", line 352, in add
def add(self, (s, p, o)):
ValueError: need more than 2 values to unpack
答案 0 :(得分:2)
您尝试将“方法”与str
连接起来,这意味着iw.next
是方法的“指针”,iw.next()
将是它的返回值,这就是你想。
明确:
line3 +=''+synset_offset+'\lemon.lexical_entry\ '+iw.next()+'/n'
更新(关于下一个错误):
triple
必须是包含3个元素的tuple
,就像函数签名所说:
add(self, (s, p, o))
忽略self
,因为您正在调用实例方法。
我很确定triple
有另一种类型,所以请检查一下(最简单的方法是print triple
语句中的for
。
