如何使用 python 在包含特定单词的文档中获取句子？

Question

从整个文本中，我想提取出现给定单词的整个句子。例如：text = "The cat ran. I am Sam. Whoop dee doo." output = get_sentence("am")应该产生 -->"I am Sam."

Answer 1

您可以使用nltk库来标记句子

nltk.download("punkt")

text = "Hello, I am Taksh. Nice to meet you Mr. Panchal. 

                    You scored 82.5 % in test"

nltk.tokenize.sent_tokenize(text)

>> ['Hello, I am Taksh.',

    'Nice to meet you Mr. Panchal.',

    'You scored 82.5 % in test']

Answer 2

将字符串拆分为句子，然后在每个句子中搜索该短语

text = text.split('. ')

for s in text:

    if searchWord in s:

        return s + "."

    return "Search word not found"

Answer 3

text = "The cat ran. I am Sam. Whoop dee doo."

text =  text.split('.')

data = input("Enter the String want to search")

for i in text:

   if data in i:

      print(i )

   else:

      print("search word is not present")
