创建进度更新方法
 

def update_progress(progress):progress_bar['value'] = progressprogress_window.update_idletasks()

调用下载方法，传入进度更新方法
 

ls_setoption.get_dump_video(video_dir, progress_callback=update_progress)progress_window.destroy()

使用子线程调用下载方法，注意用子线程，否则下载过程UI会卡死，进度不更新
 

    download_thread = threading.Thread(target=download)download_thread.start()
