How to download output files on kaggle

The output file has no download option, what should I do?

Then pack the output into a compressed package, and the download option will appear

import os
import zipfile
import datetime

def file2zip(packagePath, zipPath):
    '''
  :param packagePath: 文件夹路径
  :param zipPath: 压缩包路径
  :return:
  '''
    zip = zipfile.ZipFile(zipPath, 'w', zipfile.ZIP_DEFLATED)
    for path, dirNames, fileNames in os.walk(packagePath):
        fpath = path.replace(packagePath, '')
        for name in fileNames:
            fullName = os.path.join(path, name)
            name = fpath + '\\' + name
            zip.write(fullName, name)
    zip.close()


if __name__ == "__main__":
    # 文件夹路径
    packagePath = '/kaggle/working/'
    zipPath = '/kaggle/working/output.zip'
    if os.path.exists(zipPath):
        os.remove(zipPath)
    file2zip(packagePath, zipPath)
    print("打包完成")
    print(datetime.datetime.utcnow())
