How to compress with 7zip instead of zip, code changing

Question

I have a code that compress every file in a specific folder with zip but I want to compress it with 7zip, so how to do ?

This is what I have so far:

Answer 1

There doesn't appear to be a good Python module for creating a 7z archive (despite what the documentation says, py7zlib can only read them).

A workaround is to download the 7z SDK (http://www.7-zip.org/sdk.html) and use the 7zr executables that come with it via the subprocess module. 7z is in the public domain so you can carry this standalone program around without restriction.

Answer 2

You can try the command line method

import subprocess
subprocess.call(['7z', 'a', filename+'.7z', filename])

or for all files in folder

subprocess.call(['7z', 'a', filename+'.7z', "*.*"])
