python特定段落的文本匹配

问题描述

a=’’’[Scene: Central Perk, Chandler, Joey, Phoebe, and Monica are there.]Monica: There’s nothing to tell! He’s just some guy I work with!Joey: C’mon, you’re going out with the guy! There’s gotta be something wrong with him!Chandler: All right Joey, be nice.? So does he have a hump? A hump and a hairpiece?Phoebe: Wait, does he eat chalk?[Scene: Chandler, Joey,abcsde.]Phoebe: Just, ’cause, I don’t want her to go through what I went through with Carl- oh!Monica: Okay, everybody relax. This is not even a date. It’s just two people going out to dinner and- not having sex.Chandler: Sounds like a date to me.[Scene: Joey.]’’’

我有一段文本a，如上，我想取得每个场景的对话文本，保存成lsit,每个场景的区分是[Scene: 加一句英文.],如上面加粗的部分然后用正则表达式写，paragraphs = re.findall(’[Scene: w+.](.*?)[Scene: w+.]’,a,re.S)

我发现没有匹配出内容来，paragraphs是个空的,请问错误的原因在哪，该如何去匹配每一场景的对话内容？谢谢。

问题解答

错误有几点没有使用原生字符串没有转义[

以下是我修改后的代码。

paragraphs = re.findall(r'[Scene: [ws,]+.]s([^[]+)s(?=[Scene: [ws,]+.])', a, re.S)
