pyzstd 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.
