如何从文本文件上下文菜单运行python脚本并将其与其他文本文件进行比较？

Question

I wrote a python script that takes two files as input and then saves the difference between them as output in another file.

I bound it to a batch file .cmd (see below) and added the batch file to context menu of text files, so when I right-click on a text file and select it, a cmd window pops up and I type the address of the file to compare.

Batch file content:

@echo off
cls
python "C:\Users\User\Desktop\Difference of Two Files.py" %1

Python Code:

import sys
import os

f1 = open(sys.argv[1], 'r')
f1_name = str(os.path.basename(f1.name)).rsplit('.')[0]

f2_path = input('Enter the path of file to compare: ')
f2 = open(f2_path, 'r')
f2_name = str(os.path.basename(f2.name)).rsplit('.')[0]

f3 = open(f'{f1_name} - {f2_name} diff.txt', 'w')
file1 = set(f1.read().splitlines())
file2 = set(f2.read().splitlines())

difference = file1.difference(file2)

for i in difference:
    f3.write(i + '\n')

f1.close()
f2.close()
f3.close()

Now, my question is how can I replace the typing of 2nd file path with a drag and drop solution that accepts more than one file.

I don't have any problem with python code and can extend it myself to include more files. I just don't know how to edit the batch file so instead of taking just one file by typing the path, it takes several files by drag and drop.

I would appreciate your help.

Answer 1

Finally, I've figured it out myself! I Post the final code, maybe it helps somebody.

# This script prints those lines in the 1st file that are not in the other added files
# and saves the results into a 3rd file on Desktop.

import sys
import os


f1 = open(sys.argv[1], 'r')
f1_name = str(os.path.basename(f1.name)).rsplit('.')[0]
reference_set = set(f1.read().splitlines())

compare_files = input('Drag and drop files into this window to compare: ')
compare_files = compare_files.strip('"').rstrip('"')
compare_files_list = compare_files.split('\"\"')
compare_set = set()

for file in compare_files_list:
    with open(os.path.abspath(file), 'r') as f2:
        file_content = set(f2.read().splitlines())
    compare_set.update(file_content)


f3 = open(f'C:\\Users\\User\\Desktop\\{f1_name} diff.txt', 'w')

difference = reference_set.difference(compare_set)

for i in difference:
    f3.write(i + '\n')

f1.close()
f3.close()

The idea came from this fact that drag and drop to cmd , copies the file path surrounded with double-quotes into it. I used the repeated double-quotes between paths to create a list, and you can see the rest in the code. However, there's a downside and it's that you can't drag multiple files together and you should do that one by one, but it's better than nothing. ;)
