def get_latest_folder(path):
    try:
        lists = os.listdir(path)         # 列出目录的下所有文件和文件夹保存到lists
        lists.sort(key=lambda fn: os.path.getmtime(path + "/" + fn)) # 按时间排序
        file_new = os.path.join(path, lists[-1])      # 获取最新的文件保存到file_new
        print('In path {} the latest folder is {}'.format(path, file_new))
    except Exception as Err:
        print("Exception Reason: '{}'".format(str(Err)))
    finally:
        return file_new
