Python對比兩個文件夾中文件並篩選出差異文件

import os
import shutil


def diff_file(path1, path2):
    path = 'newnew'
    fileName1 = set([_ for _ in os.listdir(path1)])
    fileName2 = set([_ for _ in os.listdir(path2)])
    diffs = fileName1.difference(
        fileName2)  # fileName1對比fileName2，fileName1中多出來的文件；注意，如果fileName2里有fileName1中沒有的文件，也不會篩選出來
    filePath = [os.path.join(path, i) for i in diffs]
    if not os.path.exists(path):
        os.mkdir(path)
    for file in filePath:
        fileName = file.split('/')[-1]
        shutil.copy(os.path.join(path1, fileName), '/'.join(file.split('/')[:-1]))
        print('復制文件--', fileName)


if __name__ == '__main__':
    # 參照路徑
    path1 = 'new1'
    # 對比路徑
    path2 = '1'
    diff_file(path1, path2)
