It loads ISO 639 reference tables (sets 1, 2, 3, and 5) into memory at import time, allowing fast lookups of language codes by name, code, or alternative name. You instantiate a Lang object with any valid identifier or name\u2014such as 'French', 'fr', 'fre', or 'fra'\u2014and retrieve the corresponding codes and metadata for that language across all five ISO 639 standards.\n\nThe library handles individual languages, language groups, macrolanguages, and deprecated codes. It recognizes alternative names (like 'Valencian' for Catalan), provides language type and scope information, and includes utilities like is_language() for validation and iter_langs() for iteration. It requires Python 3.9 or later and has no external dependencies.","worth_installing":"Yes, if you need reliable ISO 639 language code resolution. The package is stable, dependency-free, and actively maintained. Aging maintenance status (last release 387 days ago) is not a blocker for a reference-data library, but verify that the bundled ISO 639 tables meet your currency requirements\u2014the fact sheet notes they were last updated in July 2025."},"id":"iso639-lang","links":{"html":"https://skillfed.io/packages/iso639-lang","md":"https://skillfed.io/packages/iso639-lang.md","pypi":"https://pypi.org/project/iso639-lang/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-07-23","license_spdx":null,"license_treatment":"permissive","name":"iso639-lang","python_support":"supports_current","summary":"A fast, comprehensive, ISO 639 library."},"popularity":{"monthly_downloads":423257,"position":6774,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.6.3"}
