Python 在句子列表中查找单词列表并返回匹配的句子
从句子列表和单词列表中,仅当所有三个单词都与单词列表(三叉图)匹配时,如何返回句子列表 请建议。下面是示例列表Python 在句子列表中查找单词列表并返回匹配的句子,python,nlp,nltk,list-comprehension,trigram,Python,Nlp,Nltk,List Comprehension,Trigram,从句子列表和单词列表中,仅当所有三个单词都与单词列表(三叉图)匹配时,如何返回句子列表 请建议。下面是示例列表 listwords = [['people','suffering','acute'], ['Covid-19','Corona','like'], ['people','must','collectively']] listsent = ['The number of people suffering acute hunger could almost double.',
listwords = [['people','suffering','acute'], ['Covid-19','Corona','like'], ['people','must','collectively']]
listsent = ['The number of people suffering acute hunger could almost double.',
'Lockdowns and global economic recession have',
'one more shock – like Covid-19 – to push them over the edge',
'people must collectively act now to mitigate the impact']
输出列表应该是第一句和最后一句,因为它们在listwords中有三个匹配的单词
预期产出为:
['The number of people suffering acute hunger could almost double.',
'people must collectively act now to mitigate the impact']
欢迎来到堆栈溢出 请尝试以下解决方案:
listwords = [['people','suffering','acute'], ['Covid-19','Corona','like'], ['people','must','collectively']]
listsent = ['The number of people suffering acute hunger could almost double.',
'Lockdowns and global economic recession have',
'one more shock – like Covid-19 – to push them over the edge',
'people must collectively act now to mitigate the impact']
# interate through each sentence
for sentence in listsent:
# iterate through each group of words
for words in listwords:
# check to see if each word group is in the current sentence
if all(word in sentence for word in words):
print(sentence)
我对这些行进行了评论,让你了解发生了什么
代码的第一部分遍历列表中的每个句子
for sentence in listsent:
然后我们需要遍历单词列表中的单词组
for words in listwords
这就是事情变得有趣的地方。因为你有嵌套列表,我们需要检查以确保在句子中找到所有三个单词
if all(word in sentence for word in words):
最后,您可以打印出包含所有单词的每个句子
print(sentence)
您还可以将其放入函数中,并将找到的句子作为新列表返回
listwords = [['people','suffering','acute'], ['Covid-19','Corona','like'], ['people','must','collectively']]
listsent = ['The number of people suffering acute hunger could almost double.',
'Lockdowns and global economic recession have',
'one more shock – like Covid-19 – to push them over the edge',
'people must collectively act now to mitigate the impact']
def check_words(listwords, listsent):
listsent_new = []
# interate through each sentence
for sentence in listsent:
# iterate through each group of words
for words in listwords:
# check to see if each word group is in the current sentence
if all(word in sentence for word in words):
listsent_new.append(sentence)
return listsent_new
if __name__ == '__main__':
print(check_words(listwords, listsent))
添加预期输出
