从文本文件中读取行,反向并保存在新的文本文件中

Question

到目前为止,我有这个代码:

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

原始文件中的文本是:

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,新文件如下所示:

 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:

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

我怎样才能做到这一点？

Answer 1

你可以这样做:

with open('test.txt') as f,  open('output.txt', 'w') as fout:
    fout.writelines(reversed(f.readlines()))

Answer 2

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()
