3. Use compression.zstd for standard-library Zstandard

In Python 3.14 and later, prefer compression.zstd for basic Zstandard support instead of reaching for a third-party dependency immediately.

That can simplify packaging and deployment when basic compression support is enough and you prefer standard-library availability over a third-party dependency. As with other standard modules, the advantage is mostly consistency and reduced dependency surface.

Note

Python 3.14+

3.1. Don’t do this

import zstandard

data = zstandard.ZstdCompressor().compress(b'hello world')

3.2. Do this

from compression import zstd

data = zstd.compress(b'hello world')
