Python 写入它的文件夹路径

我有下面的代码。请帮我写下它的“输入”和“输出”文件夹路径。 例如：

"input": C: \ Users \ Name \ Desktop \ Input \ *. Txt

"output": C: \ Users \ Name \ Desktop \ Output \ * .txt (it creates new txt)

输入中的txt文件名保存输出

并从包含许多txt文件的文件夹中删除“%”，然后将其导出到另一个文件夹

   f1 = open('trang.txt', 'r')
   f2 = open('trang2.txt', 'w')
   for line in f1:
       f2.write(line.replace('%', ''))
   f1.close()
   f2.close()

我使用python 3.6.2，根据您提供的输入、问题中的预期输出和注释，我已经编写了解决您问题的代码

就我而言：

• 输入目录：

  C:\Users\pc user\Desktop\Input

• 输出目录：

  C:\Users\pc user\Desktop\Output

我有3个文件

A.txt

，

B.txt

和

C.txt

在Input目录中，内容如下

正如你们在问题中提到的，你们必须使用你们自己的路径

»

C:\\Users\\pc user\\Desktop\\Input\\A.txt

»

C:\\Users\\pc user\\Desktop\\Input\\B.txt

»

C:\\Users\\pc user\\Desktop\\Input\\C.txt

复制以下代码，用自己的路径替换input_dir和output_dir变量的值，然后运行

»

Python代码

一旦上述代码成功执行，它将把输入目录中的所有文本文件写入输出目录。在我的例子中，Output目录中的内容如下所述：

»

C:\\Users\\pc user\\Desktop\\Output\\A.txt

»

C:\\Users\\pc user\\Desktop\\Output\\B.txt

»

C:\\Users\\pc user\\Desktop\\Output\\C.txt

@Monso，你的问题不清楚。请补充更多解释。为什么要读取trang.txt并写入trang2.txt等。提供更多输入和预期输出。您想将输入目录中的所有可用文件复制到输出目录吗？当我运行它时，trang.txt创建了trang2.txt，trang2.txt将被删除%，您能帮我为它写“输入”和“输出”路径吗？在“输入”中有多个txt文件。然后依次编辑每个文件并导出到一个新文件夹@rishikeshagrawani trang.txt中的内容是什么？为什么要将

%

替换为

'

？你写程序的初衷是什么？你为什么要删除trang2.txt？是的，我会帮助你，这就是为什么我要求输入。它工作得很好。我真的非常感谢你。你解释得很清楚。真的谢谢你没问题。祝你好运，你有空。请帮我再写一段代码。非常感谢你，当然。告诉我我能帮你什么忙吗？简要说明您的问题。Ibox facebook“Tu”ấn Hồ "
