Instead of writing imperative parsing code, you describe your data structure once\u2014specifying fields, their types, sizes, and relationships\u2014and Construct uses that definition in both directions: to parse binary data into Python objects and to build those objects back into binary. The library supports atomic constructs (integers, bytes, strings) and composite ones (structs, sequences, arrays, bitwise fields), plus advanced features like conditional branching, lazy parsing, pointers, and compression tunneling.\n\nIt's designed for developers who work with binary protocols, file formats, or network packets and want to avoid hand-rolling parse/build logic. The symmetry means your format definition is the single source of truth, reducing bugs and maintenance burden. Construct supports Python 3.6 through 3.11 and has no runtime dependencies, making it lightweight to add to any project.","worth_installing":"Yes. Construct is stable, permissive-licensed, dependency-free, and well-suited for any project involving binary data parsing or building. The aging maintenance status (last release 989 days ago) is a minor concern but not a blocker\u2014the API is mature and the repository remains active. Install it if you need declarative binary format handling."},"id":"construct","links":{"html":"https://skillfed.io/packages/construct","md":"https://skillfed.io/packages/construct.md","pypi":"https://pypi.org/project/construct/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2023-11-29","license_spdx":null,"license_treatment":"permissive","name":"construct","python_support":"supports_current","summary":"A powerful declarative symmetric parser/builder for binary data"},"popularity":{"monthly_downloads":7211974,"position":1768,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.10.70"}
