如何在迭代三个Lists后创建一个Python词典来匹配单词？

Question

我需要在迭代三个LISTs.为匹配的句子(list_sent为KEYs)和匹配的关键词(list_keywords)的单词列表(list_wordset为VALUEs)后创建一个Dictionary。请看下面的LISTs和预期输出的Dictionary，并加以说明。 请提出建议。

list_sent = ['one more shock like Covid-19',
             'The number of people suffering acute',
             'people must collectively act now',
             'handling the novel coronavirus outbreak',
              'After a three-week nationwide',
              'strengthening medical quarantine']

list_wordset = [['people','suffering','acute'],
                ['Covid-19','Corona','like'], 
                ['people','jersy','country'],
                ['novel', 'coronavirus', 'outbreak']]

list_keywords = ['people', 'Covid-19', 'nationwide','quarantine','handling']

'Covid-19'这个关键词在list_sent和list_wordset中都有出现，所以在Dictionary中也要抓取。'people'这个关键词在list_sent中的2个不同项目和list_wordset中的2个不同列表中都有出现，所以需要抓取。 即使list_wordset中的单个单词与关键词匹配，也是匹配的。

预期的输出是

out_dict =

{'one more shock like Covid-19': ['Covid-19','Corona','like'],
 'The number of people suffering acute': [['people','suffering','acute'],['people','jersy','country']],
 'people must collectively act now' : [['people','suffering','acute'],['people','jersy','country']]}

Answer 1

>>> {sent: [
    wordset for wordset in list_wordset if any(word in sent for word in wordset)
] for sent in list_sent}
{'one more shock like Covid-19': [['Covid-19', 'Corona', 'like']], 
 'The number of people suffering acute': [['people', 'suffering', 'acute'], ['people', 'jersy', 'country']], 
 'people must collectively act now': [['people', 'suffering', 'acute'], ['people', 'jersy', 'country']], 
 'handling the novel coronavirus outbreak': [['novel', 'coronavirus', 'outbreak']], 
 'After a three-week nationwide': [], 
 'strengthening medical quarantine': []}

Answer 2

我能够使用所有3个列表，以Dictionary格式创建所需的输出。 要删除空值，使用了额外的步骤。

out_dict = {sent: [wordset for wordset in list_wordset if any(key in sent and key in wordset for key in list_keywords)]
 for sent in list_sent}

结果。

{'one more shock like Covid-19': [['Covid-19', 'Corona', 'like']],
 'The number of people suffering acute': [['people', 'suffering', 'acute'],
  ['people', 'jersy', 'country']],
 'people must collectively act now': [['people', 'suffering', 'acute'],
  ['people', 'jersy', 'country']],
 'handling the novel coronavirus outbreak': [],
 'After a three-week nationwide': [],
 'strengthening medical quarantine': []}

要删除空列表的值。

out_dict = dict( [(k,v) for k,v in out_dict.items() if len(v)>0])

最终结果：

{'one more shock like Covid-19': [['Covid-19', 'Corona', 'like']],
 'The number of people suffering acute': [['people', 'suffering', 'acute'],
  ['people', 'jersy', 'country']],
 'people must collectively act now': [['people', 'suffering', 'acute'],
  ['people', 'jersy', 'country']]}
