我有以下srt（字幕）文件：
import pysrt
srt = """
01
00:02:14,000 --> 00:02:18,000
I understand how customers do their choice. So
02
00:02:19,000 --> 00:02:24,000
what is the choice of packaging that they prefer when they have to pick up something in a shelf?
03
00:02:24,000 --> 00:02:29,000
What is the choice of the store where they will go shopping? What specific
04
00:02:29,000 --> 00:02:34,000
product they will purchase and also what is the brand that they will
05
00:02:34,000 --> 00:02:39,000
prefer. And of course many of the choices that are relevant in the context of marketing.
"""
您会看到字幕奇怪地分开了。我希望每个字幕都以完整的句子结尾，例如：
srt = """

我想知道如何使用python实现这一目标。 可以使用pysrt打开字幕文本：
import pysrt
srt = """

with open("test.srt", "w") as text_file:
text_file.write(srt)
sub = pysrt.open("test.srt")
text = sub.text

根据@Chris的答案，我尝试了：
from operator import itemgetter
srt = """

l = [s.split('\n') for s in srt.strip().split('\n\n')]

但是我得到的结果与输入的完全一样...

我做错了什么？ Ay帮助将不胜感激。
答案 0 :(得分：2)
这有点混乱，并且容易出错，但是可以按预期工作：
from operator import itemgetter
l = [s.split('\n') for s in srt.strip().split('\n\n')]
whole = ' '.join(map(itemgetter(2), l))
for i, sen in enumerate(re.findall(r'([A-Z][^\.!?]*[\.!?])', whole)):
l[i][2] = sen
print('\n\n'.join('\n'.join(s) for s in l))
输出：
01
00:02:14,000 --> 00:02:18,000
I understand how customers do their choice.
02
00:02:19,000 --> 00:02:24,000
So what is the choice of packaging that they prefer when they have to pick up something in a shelf?
03
00:02:24,000 --> 00:02:29,000
What is the choice of the store where they will go shopping?
04
00:02:29,000 --> 00:02:34,000
What specific product they will purchase and also what is the brand that they will prefer.
05
00:02:34,000 --> 00:02:39,000
And of course many of the choices that are relevant in the context of marketing.
