不从打印返回任何内容

Question

我正在尝试读取图像并进行处理，然后输出处理后的图像。但是，该代码在我的计算机上不返回任何内容（在工作目录中可以找到zip文件）。我试图将文件中的项目打印出来。但是什么也没打印。谁能告诉我这是怎么回事？？？非常感谢！

        if file.endswith(".zip") and file.startswith("train"):
            ziplist.append(file)
    print(ziplist)
    # import data
    labels = []  #list of file names without suffix
    #img = []

    #os.mkdir(args.thumb_dir)

    for file in ziplist:
        count += 1
        #os.mkdir(args.thumb_dir + str(file))
