正規表現を使用して10進数の文全体を抽出します

Question

正規表現を使用して、単語「R & D」を含む文を抽出しようとしています。

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] 

出力： 私のコードは

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

は、私はあなたがすべての英数字と英数字以外の文字に一致するように[\w\W]とR&Dを囲むことができThe third quarter R&D spending was 2.
