在句子列表中查找单词列表并返回匹配的句子

Question

从句子列表和单词列表中，如何返回句子列表，仅当单词列表(Trigram(中的三个单词都匹配时。

请提出建议。以下是示例列表。

listwords = [['people','suffering','acute'], ['Covid-19','Corona','like'], ['people','must','collectively']]
listsent = ['The number of people suffering acute hunger could almost double.',
'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个&最后一句，因为它们在listwords中有三个匹配的单词。

预期输出为：

['The number of people suffering acute hunger could almost double.',
'people must collectively act now to mitigate the impact']

欢迎使用堆栈溢出

试试这个解决方案：

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)

我评论了这些行，让你了解的情况

代码的第一部分迭代列表中的每一句话

for sentence in listsent:

然后我们需要迭代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。由于您有嵌套列表，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，你可以打印出包含所有单词的每个句子

print(sentence)

你也可以把它放在一个函数中，并将找到的句子作为一个新的列表返回

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))
