Question

我想在标识为NNS的单词周围添加方括号。能够将其识别为单个单词，如何将其与句子重新结合。

import spacy, re

nlp = spacy.load('en_core_web_sm')
s = u"The cats woke up but the dogs slept."

doc = nlp(s)
for token in doc:
    if (token.tag_ == 'NNS'):
        print ([token])

当前结果：

[cats]
[dogs]

预期结果：

The [cats] woke up but the [dogs] slept.

Answer 1

一个常见的习惯用法是使用列表来收集单词，然后将它们加入：

sentence = []
doc = nlp(s)
for token in doc:
    if (token.tag_ == 'NNS'):
        sentence.append('[' + token + ']')
    else:
        sentence.append(token)

sentence = ' '.join(sentence)

Answer 2

@John Blart，答案是使用列表理解的正确选择：

import spacy

nlp = spacy.load('en_core_web_sm')
s = u"The cats woke up but the dogs slept."

doc = nlp(s)
print(' '.join(['[{}]'.format(token) if token.tag_ == 'NNS' else '{}'.format(token) for token in doc])

Answer 3

import spacy

nlp = spacy.load('en_core_web_sm')
s = u"The cats woke up but the dogs slept."
doc = nlp(s)
sentence = []
doc = nlp(s)
for token in doc:
    if (token.tag_ == 'NNS'):
        sentence.append('[' + (token.text) + ']')
    else:
        sentence.append(token.text)

sentence = ' '.join(sentence)
print sentence

结果：

The [cats] woke up but the [dogs] slept .
