合并2个字幕块时遇到问题

Question

我正在尝试合并2个字幕块，以便更轻松地使用deepl。虽然句子可以合并并且结束时间改变但我在更改索引号时遇到了麻烦。 count变量递增但从未从索引中减去。

例如，如果我们有这个字幕块：

5
00:00:23,315 --> 00:00:25,108
A streetwise but soulful
teen needed somewhere to live

6
00:00:25,192 --> 00:00:26,610
as he waited for his Juilliard audition.

7
00:00:26,693 --> 00:00:29,488
We'd support his dancing and let
him stay in the guest room, right.

5和6将合并。结束时间将是6.那个工作很好，除非它合并时我应该得到5和6的索引，但我得到5和7。

我想要做的例子：

5
00:00:23,315 --> 00:00:26,610
A streetwise but soulful
teen needed somewhere to live
as he waited for his Juilliard audition.

6
00:00:26,693 --> 00:00:29,488
We'd support his dancing and let
him stay in the guest room, right.

这是我的代码。我尝试添加2个地方，尝试了subs[sub.index].index = subs[sub.index] - count，但没有一个工作。

import pysrt
import os

count = 0

# Init pysrt
subs = pysrt.open(" Bojack Horseman36.srt")
# Go through each subtitle
for sub in subs:
    try:
        # Check if it's a sentence if not check if there is another sentence there if not nothing just remove index
        sentence = None
        if subs[sub.index].text.endswith('.') or subs[sub.index].text.endswith('?') or subs[sub.index].text.endswith('!'):
            subs[sub.index].index - count
        else:
            subs[sub.index].text = subs[sub.index].text + '\n' + subs[sub.index+1].text
            count+=1
            subs[sub.index].index - count
            subs[sub.index].end = subs[sub.index+1].end
            del subs[sub.index+1]
    except IndexError:      
        pass

subs.save('translatedsubs.srt', encoding='utf-8')

任何帮助都将不胜感激，谢谢：D

以下内容可以帮助您入门：

import pysrt

subs = pysrt.open("test.srt")
append_index = None
remove_list = []                # List of unwanted indexes
sub_index = subs[0].index       # Existing starting index

for index, sub in enumerate(subs):
    if append_index is not None:
        subs[append_index].text += "\n" + sub.text
        subs[append_index].end = sub.end
        remove_list.append(index)
    if sub.text[-1] not in '.?!':
        append_index = index
    else:
        append_index = None

# Remove orphaned subs in reverse order        
for index in remove_list[::-1]:     
    del subs[index]

# Reindex remaining subs
for index in range(len(subs)):
    subs[index].index = index + sub_index

subs.save('test out.srt', encoding='utf-8')

如果连续需要多个连接，它可能会遇到问题。

它产生以下输出：

5
00:00:23,315 --> 00:00:26,610
A streetwise but soulful
teen needed somewhere to live
as he waited for his Juilliard audition.

6
00:00:26,693 --> 00:00:29,488
We'd support his dancing and let
him stay in the guest room, right.

请注意，最好不要删除或添加正在迭代的列表中的项目。相反，我创建了一个要删除的索引列表。然后以相反的顺序删除不需要的索引，这样，要删除的其余项的索引保持不变。
