Instead of cryptic assert statements or unittest methods, you chain readable clauses like `.is_an(int)`, `.contains()`, and `.has_key()` to express what you expect. The library raises informative EnsureError exceptions with clear messages when checks fail, making it useful for both test code and production validation (e.g., API input checking).\n\nThe package depends only on six and installs as a pure Python wheel. It supports Python 3.6 through 3.11 and includes a decorator, @ensure_annotations, for enforcing function signature type hints at runtime. Because ensure doesn't use the assert statement (which can be disabled with Python's -O flag), validations remain active in optimized production deployments.","worth_installing":"Yes, if you want readable assertions in tests or production validation. The library is stable, has no known vulnerabilities, and adds minimal install friction. The dormant maintenance (no updates since late 2023) is a minor concern but not a blocker\u2014the API is mature and the codebase is simple. Suitable for projects prioritizing readable validation code over framework integration."},"id":"ensure","links":{"html":"https://skillfed.io/packages/ensure","md":"https://skillfed.io/packages/ensure.md","pypi":"https://pypi.org/project/ensure/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2023-12-10","license_spdx":null,"license_treatment":"permissive","name":"ensure","python_support":"supports_current","summary":"Literate BDD assertions in Python with no magic"},"popularity":{"monthly_downloads":863431,"position":4868,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.0.4"}
