我想从键值列表样式的数据的句子中搜索关键字，并返回与句子引用匹配的句子。我一直在研究checkSentence（）。我知道怎么写才能只得到报价结果：
def checkSentence(quote_list, searchItems):
result_sentence = [all([searchingWord in searchingSentence for searchingWord in searchItems]) for searchingSentence in quote_list]
return [quote_list[i] for i in range(0, len(result_sentence)) if result_sentence[i]]
checkResult = checkSentence(quote_list, searchItems)
quoteResult_list = []
for quote in checkResult:
quoteResult_list.append(quote)
print(len(quoteResult_list))
print(quoteResult_list)
现在，我想使其带有引用（“文章”）的句子（数据中的“内容”）。就像是“世界由甜蜜组成。”：“世界”。
应该有两个for循环，第一层是句子搜索，第二个for循环应该获取句子的“文章”。我不知道为什么它不起作用？看来错误在item_list [“ quote”]和item_list [“ article”]？非常感谢！
代码如下：
import json
import os
# data part
data = {
"title": "Vulnerable",
"items": [
{
"article": "The World",
"content": [
"The world is made of sweet.",
"The sweet tastes so good.",
]
},
{
"article": "The Disaster",
"content": [
"That is the sweet wrapping with poison.",
"Is that true? Are you kidding?",
]
},
{
"article": "The Truth",
"content": [
"Trust me. That is not sweet!",
"You see? That is why!",
]
}
]
}
# keywords for searching
searchItems = ["sweet", "is"]
# deal with data to list
item_list = []
quote_list = []
article_list = []
for item in data["items"]:
article = item["article"]
for quote in item["content"]:
item_list.append({article, quote})
quote_list.append(quote)
article_list.append(article)
# check if sentences include keywords
def checkSentence(item_list, searchItems):
for sentence in item_list["quote"]:
result_sentence = [all([searchingWord in searchingSentence for searchingWord in searchItems]) for searchingSentence in sentence]
sententceResult = [item_list[i] for i in range(0, len(result_sentence)) if result_sentence[i]]
for article in item_list["article"]:
return_article = [all([searchingWord in searchingSentence for searchingWord in searchItems]) for searchingSentence in article]
quoteResult = [item_list[i] for i in range(0, len(return_article)) if return_article[i]]
return sententceResult, quoteResult
# make the searching result as list item
checkResult = checkSentence(item_list, searchItems)
quoteResult_list = []
for quote in checkResult:
quoteResult_list.append(quote)
print(quoteResult_list)
在添加文章和引号以item_list使用元组时，因为这样可以更轻松地找到匹配项：
item_list.append((article, quote))
现在到checkSentence函数：
因为现在我们正在使用元组，所以我们可以同时保存文章和相应的句子。然后，您只需搜索中的关键字sentence，如果匹配，则将article和都添加sentence到matches列表中。之后，您只需返回他的结果列表即可。
这是最终代码（无数据）：
# keywords for searching
searchItems = ["sweet", "is"]
# deal with data to list
item_list = []
quote_list = []
article_list = []
for item in data["items"]:
article = item["article"]
for quote in item["content"]:
# use tuples to make later use easier
item_list.append((article, quote))
quote_list.append(quote)
article_list.append(article)
# check if sentences include keywords
def checkSentence(item_list, searchItems):
matches = []
# unpack the tuples and iterate over the list
for article, sentence in item_list:
# check for matching key words in sentence
if all([searchingWord in sentence for searchingWord in searchItems]):
# add both article and sentence to the matches, if key words are present
matches.append((article, sentence))
return matches
# make the searching result as list item
checkResult = checkSentence(item_list, searchItems)
print(checkResult)
