It solves the problem of determining which modules are part of the standard library for a given Python version\u2014useful for static analysis tools, linters, and import sorters that need to distinguish standard library imports from third-party ones.\n\nThe package provides module name lists for each major CPython release from 2.3 onward, plus combined views across all 2.x and 3.x releases. On Python 3.10+, the runtime provides `sys.stdlib_module_names`, but stdlibs exists to offer historical records, pre-release listings, and a broader set of importable modules that aren't always included in the official runtime list. It's used by tools like Ruff and \u00b5sort.","worth_installing":"Yes. This is a lightweight, actively maintained reference package with zero dependencies, permissive licensing, and clear utility for static analysis and tooling. Install it if you're building linters, import sorters, or any tool that needs to reliably distinguish standard library modules from third-party ones across multiple Python versions."},"id":"stdlibs","links":{"html":"https://skillfed.io/packages/stdlibs","md":"https://skillfed.io/packages/stdlibs.md","pypi":"https://pypi.org/project/stdlibs/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-26","license_spdx":null,"license_treatment":"permissive","name":"stdlibs","python_support":"supports_current","summary":"List of packages in the stdlib"},"popularity":{"monthly_downloads":2672943,"position":2948,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2026.2.26"}
