# 批量重命名文件夹

        # print("root:", root)
        count = 0
        for file in files:
            # root_path + "images" + "/" + str(file)
            file_name = file.split('.')
            # print("root_path+str(file):  ", root_path + "/" + str(file))
            str = root.split('/')[-1]
            Olddir = os.path.join(path, file)
            if os.path.isdir(Olddir):
                continue

            os.rename(Olddir, Newdir)
            count += 1
