Instead of manually constructing error messages with string formatting scattered throughout your code, you define an exception class once with a `__template__` attribute and provide only the variable data as keyword arguments when raising it. The library automatically populates annotated instance attributes from those kwargs, allowing you to access structured error data programmatically rather than parsing strings.\n\nThe package targets developers who want to centralize exception message logic and treat exceptions as first-class data objects with fields. It supports class-level defaults, instance-level defaults (both static and dynamic via a `factory` helper), and inheritance hierarchies for exception specialization. With no runtime dependencies and support for modern Python versions, it integrates into existing projects with minimal friction.","worth_installing":"Yes. izulu is actively maintained, has no dependencies, installs easily, and solves a real problem\u2014centralizing exception message templates and structuring exception data. It's particularly valuable in codebases with many custom exceptions or where exception attributes need to be accessed programmatically. The permissive license and stable API make it safe for production use."},"id":"izulu","links":{"html":"https://skillfed.io/packages/izulu","md":"https://skillfed.io/packages/izulu.md","pypi":"https://pypi.org/project/izulu/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-10","license_spdx":null,"license_treatment":"permissive","name":"izulu","python_support":"supports_current","summary":"The exceptional library"},"popularity":{"monthly_downloads":662319,"position":5438,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.75.0"}
