python将一个文本文件复制到另一个文件中_使用Python逐行从一个文本文件复制到另一个文本文件...

我对Python和编程都是新手，我尝试从文本文件(包含字幕)创建srt文件

这是我的代码：with open("in3.txt") as f:

lines = f.readlines()

# lines = [l for l in lines]

with open("out.txt", "w") as f1:

for x in range(0, 7):

y = x*10

f1.write("\n00:01:"+str(y)+"\n")

f1.writelines(lines)

这就是我得到的：

00:01:0

This is 1st line

This is 2nd line

This is 3rd line

This is 4th line

This is 5th line

00:01:10

This is 1st line

This is 2nd line

This is 3rd line

This is 4th line

This is 5th line

00:01:20

This is 1st line

This is 2nd line

This is 3rd line

This is 4th line

This is 5th line

...

然而，期望的结果是：

00:01:0

This is 1st line

00:01:10

This is 2nd line

00:01:20

This is 3rd line

00:01:30

This is 4th line

in3.txt包含：This is 1st line

This is 2nd line

This is 3rd line

This is 4th line

This is 5th line

任何帮助都将不胜感激：)

谢谢
