返回包含搜索字符串的句子

Question

目标： print()句子，来自长文本，基于短语。

我可以拆分句号， sentence = sentence.split('.') 。

代码 1：

phrase = 'PHRASE'

sentence = "Foo. My sentence contains PHRASE here. Bar."
sentence = sentence.split('.')

print(sentence)

Output：

['Foo', ' My sentence contains PHRASE here', ' Bar', '']

现在，我需要能够对任何和所有句子类型进行这项工作： . ? ? . ? ? . 然后从包含phrase的列表中提取元素。

代码 2：

phrase = 'PHRASE'

sentence = "Foo. My sentence contains PHRASE here. Bar."
sentence = sentence.split('.')
sentence = [s for s in sentence if phrase in s]
sentence = sentence[0]
print(sentence)

During handling of the above exception, another exception occurred:

  File "<string>", line 1, in <module>
  File "/usr/lib/python3.8/py_compile.py", line 150, in compile

                                 ^
SyntaxError: invalid syntax

所需的 Output：

My sentence contains PHRASE here.

如果还有什么我可以添加到帖子中，请告诉我。

Answer 1

将 lambda 替换为list-comprehension 。

使用str.replace('?', '.') 。

代码：

phrase = 'PHRASE'

sentence = "Foo! My sentence contains PHRASE here! Bar?"
sentence = sentence.replace('!', '.')
sentence = sentence.replace('?', '.')
sentence = sentence.split('.')
sentence = [s for s in sentence if phrase in s]
sentence = sentence[0]
print(sentence)

追溯：

My sentence contains PHRASE here
