How can unrar a file with python

A good package for it is rarfile :

Infos and docs here :

https://pypi.python.org/pypi/rarfile/

https://rarfile.readthedocs.io/api.html

Late, but I wasn't satisfied with any of the answers.

pip install patool
import patoolib
patoolib.extract_archive("foo_bar.rar", outdir="path here")

Works on Windows and linux without any other libraries needed.

After some deep diving, here are my findings:

RAR is not an free open format and is owned by RARLabs. You must install their DLL or exe first to work with RAR. Some programs like 7zip might already include this with them.
patool is application that provides uniform command line as wrapper to other external compression applications. Natively, it can only deal with TAR, ZIP, BZIP2 and GZIP without needing external support.
pyunpack is Python library that can only deal with zip natively but provides interface to patool.

With this in mind, following things worked for me:

Then to use it,

import pyunpack

pyunpack.Archive(archive_file).extractall(extract_dir)

Try the pyunpack package:

from pyunpack import Archive
Archive('a.zip').extractall('/path/to')
