The compression package¶
The compression package contains the canonical compression modules
containing interfaces to several different compression algorithms. Some of
these modules have historically been available as separate modules; those will
continue to be available under their original names for compatibility reasons,
and will not be removed without a deprecation cycle. The use of modules in
compression is encouraged where practical.
compression.bz2 – Re-exports bz2
compression.gzip – Re-exports gzip
compression.lzma – Re-exports lzma
compression.zlib – Re-exports zlib
compression.zstd – Wrapper for the Zstandard compression library
