工作任务：要把字幕srt文档进行拆分，把数字1和16之间的提取出来，然后转成纯文本文档；
你是一个Python编程专家，要完成一个Python脚本编写任务，具体步骤如下：
读取srt文档里面的每一行："D:\My.Neighbor.Totoro.1988.720p.BluRay.X264-AMIABLE [PublicHD]\My.Neighbor.Totoro.1988.720p.BluRay.X264-AMIABLE.srt"
定位到内容为数字的那些行；
然后提取数字“{hangnumber1}”和数字“{hangnumber1}+15”之间的文本内容（{hangnumber1}从1开始，以15递增，直到608结束），删除掉所有时间轴和数字行，然后把处理后的文本内容保存为txt文档，保存在文件夹”D:\My.Neighbor.Totoro.1988.720p.BluRay.X264-AMIABLE [PublicHD]\Subs”,txt文档的格式为txt，文件名为：数字“{hangnumber1}”和数字“{hangnumber1}+15”之间的中间数；
注意：每一步都要输出信息到屏幕

ChatGPT生成了代码，但是运行时有一点小问题，多提取了一行内容，让ChatGPT修改：
下面是srt文档内容：

1
00:02:32,174 --> 00:02:34,343
Dad, do you want some candy?
2
00:02:34,426 --> 00:02:36,887

00:02:50,609 --> 00:02:51,735
Mei, hide!
5
00:02:57,658 --> 00:02:59,076
It wasn't a policeman.
6
00:02:59,326 --> 00:03:00,869
Hello!
7
00:03:31,984 --> 00:03:34,611
Hello. Are your parents around?

00:03:36,863 --> 00:03:37,948
Thanks.
9
00:03:40,284 --> 00:03:43,954
I'm Kusakabe! We've just arrived!
10
00:03:45,038 --> 00:03:46,873
A pleasure to meet you!
11
00:03:47,541 --> 00:03:49,793
Welcome!

00:03:54,298 --> 00:03:55,382
Thank you.
13
00:04:17,696 --> 00:04:18,822
Here we are!
14
00:04:20,407 --> 00:04:21,658
Wait!
15
00:04:24,578 --> 00:04:27,122
- Mei, there's a bridge!
- A bridge?
16
00:04:32,461 --> 00:04:34,504
See that flash? Fish too!
17
00:04:35,672 --> 00:04:37,090
So, you like it here?

你把数字“16”和数字“17”之间的内容“See that flash? Fish too!”也提取到了数字“1”和数字“16”之间，多提取了内容，请修正这个错误。
