Question

[('3604', 0.7113370895385742),
 ('63', 0.6787939071655273),
 ('6566', 0.6688929796218872),
 ('6406', 0.6664271354675293),
 ('15', 0.6614164113998413)]

我想获取第一个实例的索引，即：

[(log[3604], 0.7113370895385742),
 (log[63], 0.6787939071655273),
 (log[6566], 0.6688929796218872),
 (log[6406], 0.6664271354675293),
 (log[15], 0.6614164113998413)]

到目前为止，我正在这样做：

new_sentence = "My Order".split(" ")  
sen2vec.docvecs.most_similar(positive=[sen2vec.infer_vector(new_sentence)],topn=5)

获取列表。任何建议将有所帮助！

Answer 1

您可以使用以下列表理解：

l = [('3604', 0.7113370895385742),
 ('63', 0.6787939071655273),
 ('6566', 0.6688929796218872),
 ('6406', 0.6664271354675293),
 ('15', 0.6614164113998413)]
print([(log[int(i)], n) for i, n in l])

Answer 2

我猜您有一个希望通过索引访问的名为log的对象。

如果是这种情况，这不是这样做的方法吗？

a =[('3604', 0.7113370895385742),
  ('63', 0.6787939071655273),
  ('6566', 0.6688929796218872),
  ('6406', 0.6664271354675293),
  ('15', 0.6614164113998413)]

log = range(10000)

b = [(log[int(x[0])], x[1]) for x in a]
print b

从列表中获取数字索引
