Mimic 7zip with python

2020-07-17 06:15发布

I am using Python 3.6, and currently I subprocess out to my 7zip program to get the compression I need.

subprocess.call('7z a -t7z -ms=off {0} *'.format(filename))

I know the zipfile class has ‘ZIP_LZMA’ compression, but the application I am passing this too says the output file isn’t correct. So what else do I have to add to the ZipFile class to make it mimic the above command?

If you do not care much for Windows, then perhaps libarchive could help. In Ubuntu, for example:

$ sudo apt install python3-libarchive-c

Then:

import libarchive
with libarchive.file_writer('test.7z', '7zip') as archive:
    archive.add_files('first.file', 'second.file', 'third.file')

Then there is the pylib7zip library, which wraps the existing 7z.dll and seems to offer a Windows-only alternative.
