列出目录1中但不在目录2中的文件,反之亦然？

import os

def list_files_only_in_dir1(dir1, dir2):
    files_only_in_dir1 = []
    
    for root, dirs, files in os.walk(dir1):
        for file in files:
            file_path = os.path.join(root, file)
            relative_path = os.path.relpath(file_path, dir1)
            corresponding_file_path_in_dir2 = os.path.join(dir2, relative_path)
            
            if not os.path.exists(corresponding_file_path_in_dir2):
                files_only_in_dir1.append(file_path)
    
    return files_only_in_dir1

dir1 = "/path/to/dir1"
dir2 = "/path/to/dir2"

files_only_in_dir1 = list_files_only_in_dir1(dir1, dir2)

print("Files only in dir1:")
for file in files_only_in_dir1:
    print(file)
