Python在一个txt文件中合并行

Question

关于在 txt 文件中合并行的问题。

文件内容如下(电影字幕)。我想将字幕、每个段落中的那些英文单词和句子合并为 1 行，而不是现在分别显示 1、2 或 3 行。

能否请您告知哪种方法在 Python 中可行？非常感谢。

Been a while since I was up here
in front of you.

2
00:00:25,762 --> 00:00:28,847
Maybe I'll do us all a favour
and just stick to the cards.

00:00:31,935 --> 00:00:34,603
There's been speculation that I was
involved in the events that occurred
on the freeway and the rooftop...

4
00:00:36,189 --> 00:00:39,233
Sorry, Mr Stark, do you
honestly expect us to believe that

5
00:00:39,317 --> 00:00:42,903
that was a bodyguard
in a suit that conveniently appeared,

6
00:00:42,987 --> 00:00:45,698
despite the fact
that you sorely despise bodyguards?

7
00:00:45,782 --> 00:00:46,907
Yes.

8
00:00:46,991 --> 00:00:51,662
And this mysterious bodyguard
was somehow equipped

直观的解决方案

基于您可以拥有的 4 种线条的简单解决方案:

• 一个空行
• 表示位置的数字(无字母)
• 字幕的时间安排(具有特定模式；无字母)
• 正文

您可以遍历每一行，对它们进行分类，然后采取相应的行动。

事实上，非文本非空行(时间线和数字)的“ Action ”是相同的。因此:

import re

with open('yourfile.txt') as f:
    exampleText = f.read()

new = ''

for line in exampleText.split('\n'):
    if line == '':
        new += '\n\n'
    elif re.search('[a-zA-Z]', line):  # check if there is text
        new += line + ' ' 
    else:
        new += line + '\n' 

结果:

>>> print(new)

正则表达式解释:

• []表示里面的任意一个字符
• a-z表示字符a-z的范围
• A-Z表示字符A-Z的范围
