从文本文件中读取行，反转并保存在新的文本文件中 [英] Read lines from a text file, reverse and save in a new text file

问题描述

到目前为止我有这个代码:

So far I have this code:

 f = open("text.txt", "rb")
 s = f.read()
 f.close()
 f = open("newtext.txt", "wb")
 f.write(s[::-1])
 f.close()

原文件中的文字为:

This is Line 1
This is Line 2
This is Line 3
This is Line 4

当它反转并保存它时，新文件看起来像这样:

And when it reverses it and saves it the new file looks like this:

 4 eniL si sihT 3 eniL si sihT 2 eniL si sihT 1 eniL si sihT

当我希望它看起来像这样时:

When I want it to look like this:

 This is line 4
 This is line 3
 This is line 2
 This is line 1

我该怎么做?

推荐答案

f = open("text.txt", "rb")
s = f.readlines()
f.close()
f = open("newtext.txt", "wb")
s.reverse()
for item in s:
  print>>f, item
f.close()
