Features:

• supported python versions: 3.9, 3.10, 3.11, 3.12
• tested platforms: Linux, macOS, Windows
• back-ends:
  • zipfile: included in Python
  • patool: It relies on helper applications to handle those archive formats (for example bzip2 for BZIP2 archives). Supported formats: 7z (.7z), ACE (.ace), ALZIP (.alz), AR (.a), ARC (.arc), ARJ (.arj), BZIP2 (.bz2), CAB (.cab), compress (.Z), CPIO (.cpio), DEB (.deb), DMS (.dms), GZIP (.gz), LRZIP (.lrz), LZH (.lha, .lzh), LZIP (.lz), LZMA (.lzma), LZOP (.lzo), RPM (.rpm), RAR (.rar), RZIP (.rz), TAR (.tar), XZ (.xz), ZIP (.zip, .jar) and ZOO (.zoo)

Functionality

patool is called by pyunpack using its command line interface. If patool is not installed then only zip format can be unpacked using the internal python zipfile library.

Usage

$ echo hello > hello.txt
$ zip hello.zip hello.txt
$ rm hello.txt
$ python3

>>> from pyunpack import Archive
>>> Archive('hello.zip').extractall('.')
>>> open('hello.txt').read()
'hello\n'

using command line interface:

$ echo hello > hello.txt
$ zip hello.zip hello.txt
$ rm hello.txt
$ python3 -m pyunpack.cli hello.zip .
$ cat hello.txt
hello

Installation on Ubuntu

$ sudo apt-get install unzip unrar p7zip-full
$ python3 -m pip install pyunpack

Currently (2022) Patool latest pip release is from 2016 (https://pypi.org/project/patool/#history), so it is recommended to install it from github until it is not updated. Password support was added in 2020

$ python3 -m pip install https://github.com/wummel/patool/archive/refs/heads/master.zip
