'zipfile module in python to compress files

Can zipfile module be used to compress files to a 7z archive? I have to work with a set of csv files and I have been asked to 7zip these files. I wanted to know if zipfile module in python would compress these files to 7z archive.

python python-zipfile

Zipfile does not compress to 7zip archives. You can write :

with ZipFile('archive.7z', 'w'):

it will create the archive, no problem, but you cannot decompress it like a .7z, it's still a .zip (structurally) with the wrong extension at the end.

Zipfile does not support the compression method used by default in the 7zip file format, LZMA. However, you can use community provided bindings to compress a file with LZMA. Install the pylzma library to your python environment. Once the module is installed, it is pretty straight forward to compress a file.

import pylzma
compressed = pylzma.compress(my_csv.csv)

The compressed file should be acceptable for 7zip. Usage docs.
