Python bindings to Zstandard (zstd) compression library

📖 Documentation | 📃 Changelog

The pyzstd module provides Python support for Zstandard, using an API style similar to the bz2, lzma, and zlib modules.

[!WARNING]

Zstandard is now natively supported in Python’s standard library via the compression.zstd module. For older Python versions, use the backports.zstd library as a fallback.

We recommend new projects to use the standard library, and existing ones to consider migrating.

pyzstd internally uses compression.zstd since version 0.19.0.

See pyzstd's documentation for details and a migration guide.
