You inherit from the `Abstract` base class and mark required class properties using `abstract_class_property(type)`, which enforces that concrete subclasses provide a value and raises a `TypeError` if they don't. This solves a gap in Python's standard `abc` module, which has no built-in mechanism for abstract class variables.\n\nThe package is designed to be lightweight and Pythonic: it does all validation at class definition time (no runtime overhead), integrates cleanly with type hints, and produces clear error messages when a subclass forgets to define a required property. It supports multi-level inheritance\u2014an abstract class can have abstract children\u2014and works with Python 3.8 and higher.","worth_installing":"Yes, if you need to enforce required class-level configuration in inheritance hierarchies and want static type-checker support. The package is small, has no dependencies, and solves a real gap in Python's standard library. The aging maintenance status is not a blocker for a stable, narrow-scope tool, but verify that the pattern fits your use case\u2014it is not a general-purpose utility."},"id":"abstractcp","links":{"html":"https://skillfed.io/packages/abstractcp","md":"https://skillfed.io/packages/abstractcp.md","pypi":"https://pypi.org/project/abstractcp/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2024-05-20","license_spdx":null,"license_treatment":"permissive","name":"abstractcp","python_support":"supports_current","summary":"Create abstract class variables"},"popularity":{"monthly_downloads":76571,"position":14614,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.0"}
