Python: How to convert .7z to .rar or .zip?

Question

How can I convert a .7z file to a .rar or a .zip file using Python?

Answer 1

You can do this in two steps. First, uncompress the .7z file and then compress the content to zip file.

Uncompress .7z file

from lib7zip import Archive, formats

with Archive('filename.7z') as archive:
    # extract all items to the directory
    # directory will be created if it doesn't exist
    archive.extract('directory')

Compress to zip file

#!/usr/bin/env python
import os
import zipfile

def zipdir(path, ziph):
    # ziph is zipfile handle
    for root, dirs, files in os.walk(path):
        for file in files:
            ziph.write(os.path.join(root, file))

if __name__ == '__main__':
    zipf = zipfile.ZipFile('file.zip', 'w', zipfile.ZIP_DEFLATED)
    zipdir('tmp/', zipf)
    zipf.close()
