Question

我正在尝试使用正则表达式来提取包含单词＆＃34; R＆amp; D＆＃34;的句子。我的代码是

**\s[^.?!]*R&D[^.?!]*[?.!]**

我希望得到The third quarter R&D spending was 2.4 million, up approximately 100,000 from Q2 levels. SG&A expenses were 3.4 million, down 200,000 from Q2.

我得到了The third quarter R&D spending was 2.

Answer 1

您可以将R&D与[\w\W]包围，以匹配所有字母数字和非字母数字字符：

import re
s = "The third quarter R&D spending was 2.4 million, up approximately 100,000 from Q2 levels. SG&A expenses were 3.4 million, down 200,000 from Q2."
sentence = re.findall('^[\w\W]+R&D[\w\W]+$', s)[0]

输出：

'The third quarter R&D spending was 2.4 million, up approximately 100,000 from Q2 levels. SG&A expenses were 3.4 million, down 200,000 from Q2.'
