zipfile-xz

Monkey patch the standard zipfile module to enable XZ support.

Based on zipfile-deflate64 and zipfile-zstandard, which provides similar functionality but for the deflate64 algorithm. Unlike zipfile-deflate64, this package supports both compression and decompression.

Note: if you need Python2, use zipfile39 instead (it is also compatible with Python3).

Note: XZ is based on LZMA2, so the compression ratio will be similar to ZIP_LZMA.

Installation

pip install zipfile-xz

Usage

Anywhere in a Python codebase:

import zipfile_xz  # This has the side effect of patching the zipfile module to support XZ

Alternatively, zipfile_ppmd re-exports the zipfile API, as a convenience:

import zipfile_xz as zipfile

zipfile.ZipFile(...)

Compression example:

import zipfile_xz as zipfile

zf = zipfile.ZipFile('/tmp/test.zip', 'w', zipfile.ZIP_XZ, compresslevel=6)
zf.write('large_file.img')
