BZ2File

The `bz2file` library provides a file-like object for reading and writing bzip2-compressed files, backporting the `io.BZ2File` interface introduced in Python 3.3. While Python 3.3+ includes `bz2.open()` in its standard library, this standalone package serves as a drop-in replacement or for use with older Python versions (>=2.6, excluding 3.0-3.2). The current version is 0.98. It has an infrequent release cadence, being a stable backport.
