zipfile-zstd

Monkey patch the standard zipfile module to enable Zstandard support.

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

Requires python-zstandard for libzstd bindings.

Installation

pip install zipfile-zstd

Usage

Anywhere in a Python codebase:

import zipfile_zstd  # This has the side effect of patching the zipfile module to support Zstandard

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

import zipfile_zstd as zipfile

zipfile.ZipFile(...)

Compression example:

import zipfile_zstd as zipfile

zf = zipfile.ZipFile('/tmp/test.zip', 'w', zipfile.ZIP_ZSTANDARD, compresslevel=19)
zf.write('large_file.img')

Dictionaries and advanced compression parameters are not supported, sorry.
