python特定段落的文本匹配

Question

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。

Answer 1

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: [\w\s,]+\.]\s([^[]+)\s(?=\[Scene: [\w\s,]+\.])", a, re.S)
