无法扩展以zip压缩的.zip（不允许操作）

Question

I have a directory with several files. I want to create an archive with some of these files (eg only files with names listed in some array) That's my code:

import zipfile
import os

def zip_files(report_dir):
    zipf = zipfile.ZipFile('report.zip', 'w', zipfile.ZIP_STORED)
    rep = ['1', '2', 'new']
    print('RRREP ', rep)
    for root, dirs, files in os.walk(report_dir):
        for file in files:
            title = file.title().split('_')[0]
            if title in rep:
                zipf.write(os.path.join(root, file))

    zipf.close()


zip_files('')

When I try to expand the resulting archive, I receive a message

Unable to expand "report.zip" (Error 1 - Operation not permitted)

If I add all files from the directory (= if I remove if... -code), the archive can be opened without problems.

It seems that creating an empty zip file can cause some issues to some external archivers.

Your filter doesn't match anything. In the future, you could protect your archive creation with a flag and report an error if nothing matched:

at_least_one_match = False

for root, dirs, files in os.walk(report_dir):
    for file in files:
        title = file.title().split('_')[0]
        if title in rep:
            at_least_one_match = True
            zipf.write(os.path.join(root, file))


if not at_least_one_match:
    raise Exception("No files were added. Archive is empty/corrupt")
