为它写下文件夹路径

Question

我有以下代码。请帮我写一下“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。

从许多txt文件的文件夹中删除“％”并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()

我使用的是python 3.6.2

@Monso ，根据您提供的输入，问题和预期输出在评论中，我写了代码来解决你的问题。

就我而言：

• 输入目录：result_list = sorted(chain(job, apartments), key=lambda instance: instance.date)

• 输出目录：C:\Users\pc-user\Desktop\Input

我有3个文件C:\Users\pc-user\Desktop\Output，A.txt＆amp; 输入目录中的B.txt，内容如下。

  

你必须像在问题中提到的那样使用你自己的路径。

»C.txt

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

»This is %nice day%. Program %20 files %

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

»This is my nice journey with % Rishikesh. Monso is % also %% here. Monso %%%% is solving the Python problems % at % mor%ning.

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

  

复制以下代码，将 input_dir 和 output_dir 变量的值替换为您自己的路径并运行。

»This is % book. This i%s i%%s a % boy%. I kno%w P%y%t%%ho%n. %

Python code

上述代码成功执行后，会将 input_dir 中的所有文本文件写入 output_dir 。就我而言，输出目录中的内容如下所示：

»import glob import os def copy_files_to_output(input_dir, output_dir): # Creating a regex path for all text files inside Input directory input_dir_regex_path = os.path.join(input_dir, "*.txt"); # Getting list of absolute paths of all the text files inside Input directory input_files_paths = glob.glob(input_dir_regex_path); # Iterating over a list of input file names for full_path in input_files_paths: # Get text file name from absolute path file_name = full_path.split('\\')[-1] # Reading input text file # (Open file in read mode, 'r' is default here; the 2nd default parameter to open()) # You do not need to close file (if you open as follows using with statement) with open(full_path) as in_file: # Creating full path name of output text file output_file_path = output_dir + "\\" + file_name; # Create a new file inside Output directory # 'w' specifies to open file in write mode with open(output_file_path, 'w') as out_file: # Get list of lines in text file all_lines = in_file.readlines(); # Write all lines to a new file (inside Output directory) for line in all_lines: # Replace all '%' characters present in line with '' line = line.replace('%', ''); out_file.write(line); # Starting point if __name__ == "__main__": try: # Code to be executed input_dir = "C:\\Users\\pc-user\\Desktop\\Input"; # Use your own path output_dir = "C:\\Users\\pc-user\\Desktop\\Output"; # Use your own path # Call copy_files_to_output() function copy_files_to_output(input_dir, output_dir); # Operation successful print("Copy operation successful"); except Exception as error: # Code to be executed if any Exception occurs print("Exception occurred", error);

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

»This is nice day. Program 20 files

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