Python：在不改变段落顺序的情况下反转文件每个段落中的单词？

Question

我想通过反转text_in.txt文件中的单词来生成一个text_out.txt文件，如下所示：

text_in.txt 有如下两段：

Hello world, I am Here.

I am eighteen years old.

text_out.txt 应该是这样的：

Here. am I world, Hello

old. years eighteen am I

我的代码是：

filein = open ('text_in.txt', 'r+')

fileout = open ('text_out.txt', 'w')


data = filein.read()

array1 = data.split(' ')

array1.reverse()

out1 = " " .join(array1)

fileout.write(out1)

我的结果很old. years eighteen am I \nHere. am I world, Hello old. years eighteen am I \nHere. am I world, Hello

谁能帮我解决它？ 非常感谢 ！

Answer 1

你需要：

k = """Hello world, I am Here.
I am eighteen years old."""

x = k.split("\n")

x = [" ".join(i.split()[::-1]) for i in x]

k = "\n".join(x)
print(k)

输出：

Here. am I world, Hello
old. years eighteen am I

Answer 2

你为什么不试试这个？

filein = open ('text_in.txt', 'r+')

fileout = open ('text_out.txt', 'a')

fileread = filein.readlines()

for data in fileread:

    array1 = data.split(' ')

    array1.reverse()

    out1 = " " .join(array1)

    fileout.write(out1)

这里的思路是逐行读取文件内容（数据代表循环中的每一行），然后反向写入，以追加方式写入文件。
或者，您也可以使用filein.readline()一次读取一行。 这是输出：

Here. am I world, Hello
old. years eighteen am I

Answer 3

试试这个

filein = open ('text_in.txt', 'r+')

fileout = open ('text_out.txt', 'w')


data = filein.read()
out1 =  '' # initialise the empty variable
for each in data.split('\n'): # split at every instance of a newline character \n
  array1 = each.split(' ') # Use the same code
  array1.reverse()
  out1 += " " .join(array1)  + "\n" # add a new line to split

fileout.write(out1) # write

我发表评论作为解释

Answer 4

您的代码中的问题是您首先颠倒了段落的顺序，但实际上您需要保留顺序。 此外，我会使用上下文管理器（ with open(...) ）进行文件处理，以确保自动打开和关闭文件。

我会这样做：

with open("text_in.txt", 'r') as fin:
    read_data = fin.read().splitlines()        #read and split into list of paragraphs

with open("text_out.txt", 'w') as fout:
    for p in read_data:
        words = p.split()                      #split words (by whitespace)
        fout.write(' '.join(reversed(words)))  #reverse the words
        fout.write('\n')

用 \n 拆分字符串，然后将所有行一一反转。

filein = open ('text_in.txt', 'r+')
fileout = open ('text_out.txt', 'a')

data = filein.read()
array1 = data.split('\n')

for i in array1:
    array2 = i.split(' ')
    array2.reverse()
    out1 = " " .join(array2)
    fileout.write(out1)
    #print(out1)
