問題描述

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，我想取得每個(gè)場(chǎng)景的對(duì)話文本，保存成lsit,每個(gè)場(chǎng)景的區(qū)分是[Scene: 加一句英文.],如上面加粗的部分然后用正則表達(dá)式寫，paragraphs = re.findall(’[Scene: w+.](.*?)[Scene: w+.]’,a,re.S)

我發(fā)現(xiàn)沒有匹配出內(nèi)容來，paragraphs是個(gè)空的,請(qǐng)問錯(cuò)誤的原因在哪，該如何去匹配每一場(chǎng)景的對(duì)話內(nèi)容？謝謝。

問題解答

錯(cuò)誤有幾點(diǎn)沒有使用原生字符串沒有轉(zhuǎn)義[

以下是我修改后的代碼。

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