It lets you create bitstrings from hex, octal, binary, bytes, integers, floats, and files, then manipulate them through slicing, searching, replacing, and packing operations. The library provides idiomatic Python classes (Bits, BitArray, BitStream) and utility functions, making bit-level work feel natural rather than low-level.\n\nThe package is production-stable and has been actively maintained since 2006. It depends on bitarray and tibs (a newer Rust-based rewrite of the core, currently in beta). The library supports Python 3.8 through 3.14 and is widely used\u2014it ranks in the top 5000 PyPI packages by download volume. It's particularly useful for tasks like binary protocol parsing, data serialization, and bit manipulation in embedded or network contexts.","worth_installing":"Yes. bitstring is production-stable, actively maintained, has no known vulnerabilities, and low install friction. It's the standard choice for bit-level binary manipulation in Python. Install it if you need to work with binary protocols, data formats, or bit-level operations; the API is well-documented and the library is widely trusted in the community."},"id":"bitstring","links":{"html":"https://skillfed.io/packages/bitstring","md":"https://skillfed.io/packages/bitstring.md","pypi":"https://pypi.org/project/bitstring/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-03-10","license_spdx":null,"license_treatment":"permissive","name":"bitstring","python_support":"supports_current","summary":"Simple construction, analysis and modification of binary data."},"popularity":{"monthly_downloads":5910491,"position":2014,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"4.4.0"}
