About:
py7zr is a Python library and command-line tool for creating, extracting, and listing 7-zip archives. It provides full support for the 7z format with high compression ratios using algorithms like LZMA and LZMA2. The library aims to be a pure Python implementation, offering a lightweight and portable alternative to the standard p7zip utility.

Key Features:

Pure Python implementation with no external 7z binary dependency
Support for multiple compression algorithms including LZMA, LZMA2, BZip2, and Deflate
Full archive features: solid compression, multi-volume archives, and strong encryption (AES-256)
Standard library-like API for easy integration into Python projects

Use Cases:

Automating backup scripts that create compressed archives
Building Python applications that need to handle 7z files without system dependencies
Processing large datasets by compressing them into efficient 7z archives

Alternatives:

p7zip – A command-line C++ utility that py7zr can replace to avoid system dependencies in Python environments.
python-libarchive-c – A Python binding for libarchive which supports many formats, while py7zr focuses specifically on the 7z format.
