The compression package

Added in version 3.14.

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
