It provides RangeMap for key lookups across ranges, case-insensitive keyed dicts, bijective maps where values map back to keys, immutable FrozenDict, and several other utility containers like DictStack for scope management and WeightedLookup for probabilistic selection.\n\nThe package is a lightweight addition to your toolkit\u2014it has only one runtime dependency and installs as a pure Python wheel. It's actively maintained and has been in production use since 2015-02-16, making it suitable for projects that need these specific collection patterns without building custom implementations.","worth_installing":"Yes. The package offers genuine utility for common collection patterns, has low install friction, no known vulnerabilities, and is actively maintained under a permissive MIT license. Install it if your code needs any of its specialized mappings; otherwise, it's not a required dependency."},"id":"jaraco-collections","links":{"html":"https://skillfed.io/packages/jaraco-collections","md":"https://skillfed.io/packages/jaraco-collections.md","pypi":"https://pypi.org/project/jaraco-collections/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-06-21","license_spdx":"MIT","license_treatment":"permissive","name":"jaraco.collections","python_support":"supports_current","summary":"Collection objects similar to those in stdlib by jaraco"},"popularity":{"monthly_downloads":1263840,"position":4144,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"5.2.1"}
